With companies impacted by the global health crisis, many are working from home – we are too. MakerBot has received several questions about how to set up a 3D printing studio at home. MakerBot’s own industrial designer – Felipe Casteñeda – will walk through the steps he goes through in his process including:
The L6983 is an easy to use synchronous monolithic step-down regulator capable of delivering up to 3 A DC to the load. The wide input voltage range makes the device suitable for a broad range of applications. The L6983 is based on a peak current mode architecture and is packaged in a QFN16 3×3 with internal compensation thus minimizing design complexity and size.
The L6983 is available both in low consumption mode (LCM) and low noise mode (LNM) versions. LCM maximizes the efficiency at light-load with controlled output voltage ripple so the device is suitable for battery-powered applications. LNM makes the switching frequency constant and minimizes the output voltage ripple for light load operations, meeting the specification for low noise sensitive applications. The L6983 allows the switching frequency to be selected in the 200 Hz – 2.2 MHz range with optional spread spectrum for improved EMC.

QFN16 package
The EN pin provides enable/disable function. The typical shutdown current is 2 µA when disabled. As soon as the EN pin is pulled up, the device is enabled and the internal 1.3 ms soft-start takes place. The L6983 features Power Good open collector that monitors the FB voltage. Pulse-by-pulse current sensing on both power elements implements an effective constant current protection and thermal shutdown prevents thermal run-away.
The SSA3075X-R extends the Siglent SSA3000X series to add real-time spectrum analysis capabilities for intermittent and frequency-hopping signals used in commercial communications and 5G applications.
Saelig Company, Inc. has introduced the SIGLENT SSA3000X-R Real-Time Spectrum Analyzers (RTSA) which are powerful and flexible tools for complex RF spectrum and signal analysis. With a capability of 40MHz analysis bandwidth and 7.2μs 100% probability of intercept (POI), the analyzers can provide multi-dimensional data displays, advanced triggering, and RF data capturing, to assist with modern RF spectrum challenges such as frequency hopping, channel conflicts, spectrum interference, etc. These RTSAs also contain a standard tracking generator for network analysis, optional wideband digital modulation analysis, and EMI measurement. The SSA3050X-R model has a frequency range of 9kHz to 5.0GHz, while the SSA3075X-R has a range of 9kHz to 7.5GHz. The built-in tracking generators operate from 100kHz to 5.0GHz and 100kHz to 7.5GHz respectively, and a preamplifier is included as standard. Control is made easy with a 10.1” multi-touch screen, with an external mouse and keyboard also supported. A remote control is also possible via an attached PC or web browser.
Many real-world signals such as modulated communications signals, spurious interference, and pulsed or frequency-hopping transmissions are sporadic, non-recurring, or even random. Using traditional spectrum analyzers, which steadily sweep through the active spectrum, these signals can easily be missed. Real-time spectrum analysis (RTSA) uses overlapping FFTs and high-speed memory to provide a 100% probability of intercept to detect even intermittent signals. Real-time bandwidth, the maximum frequency span of overlapping FFTs, is a critical parameter for an RTSA to allow detailed analysis of a signal’s spectrum.
The SSA3000X-R analyzers can also perform in a swept or a real-time mode. A modulation analysis mode is also available for AM/FM, ASK/FSK/PSK/MSK/QAM vector signal modulation analysis and EVM evaluation, as well as data recording to a PC. An EMI measurement mode allows for pre-compliance and other RF testing. Reflection measurement VSWR and return loss measurement with Q value calculation can be accomplished using an external reflection bridge or coupler.
Applications include: broadcast monitoring, evaluation, cellular site evaluation, IoT, WiFi, Bluetooth, R&D, education, production test & maintenance.
The Siglent SSA3075X-R is a powerful and flexible tool for RF signal and network analysis. With a frequency range up to 7.5 GHz, this analyzer delivers reliable automatic measurements and multiple modes of operation, with other optional functions also offered pre-compliance, research and development, education, production, and maintenance.
Texas Instruments has announced a new IC that is a part of family of ultra-low power, dual channel, resistor programmable temperature switches that enable protection and detection of system thermal events from –40 °C to 125 °C. The TMP390-Q1 offers independent overtemperature (hot) and undertemperature (cold) detection. The trip temperatures (TTRIP) and thermal hysteresis (THYST) options are programmed by two E96-series resistors (1% tolerance) on the SETA and SETB pins. Each resistor can range from 1.05 kΩ to 909 kΩ, representing one of 48 unique values.
The values of the resistor to ground on SETA input sets the TTRIP threshold of Channel A. The value of the resistor to ground on SETB input sets the TTRIP threshold of Channel B, as well as the THYST options of 5 °C, or 10 °C for both channels, to prevent undesired digital output switching. Resistors accuracy has no impact to TTRIP accuracy.
To enable customer board-level manufacturing, the TMP390-Q1 supports a trip test function where the digital outputs are activated by exercising the SETA or SETB pin.

If you need to import an electronic design from production files (Gerbers, drills, ipc-356 test point netlist) to any MCAD, you can use ZofzPCB.com’s new feature: STEP file export.
ZofzPCB loads Gerber files automatically, converts the board outline drawing into the bare PCB solid and PCB tracks into optimally constructed faces. Using IPC-356 bare board test point file, ZofzPCB can recreate footprint information and, with a very little help of the user, construct component 3D models, on the fly. The resulting STEP AP214 file is constructed as an assembly tree, containing additional information like component designators and, if a BOM file is also loaded, component names/values.STEP file export was the most often requested feature, by ZofzPCB users, it has now been implemented.
3D model of an assembled PCB, created by ZofzPCB, can be saved as a STEP AP214 file and loaded into any MCAD. ZofzPCB provides two distinct features.
As we have seen in the previous tutorial presenting the fundamental laws of circuit analysis, Kirchoff’s Circuit Laws (KCL) are a powerful and efficient tool to compute unknown voltages and currents in any circuit. However, KCL sometimes presents the inconvenience to be repetitive and is not the fastest way to analyze more complex circuits.
There are two methods based on KCL that simplify and make the analysis of circuits more efficient: the Nodal Voltage Analysis and the Mesh Current Analysis.
We separately present in this article both methods in two sections. In each section, a real example is given to illustrate how to perform these analyses.
Nodal Voltage Analysis
Presentation
The Nodal Voltage Analysis (NVA) is based on Kirchoff’s Current Law and is used to determine unknown voltages at the nodes of a circuit. It consists of a series of steps to follow, that are abstractly listed below:
Label the essential nodes of the circuit, essential nodes consist of nodes that are the junction between three or more branches.
Choose one of the nodes to be the reference of the circuit. In most cases, it is the bottom node.
Express the currents in the branches as a function of the voltages.
Write Kirchoff’s current law at each node other than the reference node.
Example
Consider the following electronic circuit presented in Figure 1 for which we will perform an NVA. For numerical applications, we take S1=10 V and S2=2 A; R1=1 Ω, R2=5 Ω, R3=2 Ω, and R4=10 Ω.
fig 1: Example of a circuit with labeled nodes, voltages, and currents
In this circuit, we already completed steps 1 and 2, the Node 3 has been chosen as the reference (ground) of the circuit, which is indicated with a grounding symbol.
According to step number 3, we can write each current I1, I2,…, I5 as a function of V12 and V13, the currents are computed by applying Ohm’s law to each branch:
I1=(10-V13)/R1
I2=V13/R2
I3=(V13-V23)/R3
I4=V23/R4
I5=-S2=-2 A
According to step 4, we write the Kirchoff’s current law at nodes 1 and 2:
We obtain therefore a linear system of 2 equations with 2 unknown parameters that can be rewritten clearer by multiplying the lines with appropriate factors, arranging the terms and replacing the resistor and sources terms by their value:
This system can be rewritten as a matrix equation:
eq 1: Matrix equation of our example
This type of equation can easily be solved by hand or using a computer program such as MatLab, the solution is V13=9.1 V and V23=10.1 V.
Since every current is a function of these values, we can compute and list them:
I1=(10-9.1)/1=0.9 A
I2=9.1/5=1.8 A
I3=(9.1-10.1)/2=-0.5 A
I4=10.1/10=1 A
I5=-2 A
Mesh Current Analysis
Presentation
Another powerful method that simplifies the KCL such as the Nodal Voltage Analysis is presented in this section and known as the Mesh Current Analysis (MCA). Instead of focusing the analysis around the nodes such as presented for the previous method, we label the currents circulating in each mesh of the circuit. A mesh simply consists of a loop with no other internal loops in it.
We list below the following steps to perform an MCA:
Attribute and label currents on each mesh of the circuit. Usually, we choose the clockwise direction for positive currents.
Apply Kirchoff’s voltage law (KVL) for every mesh in the same direction as the currents previously stated.
Solve the loop equations that appear with the KVL analysis.
Compute the required current or voltage in the circuit thanks to the mesh currents.
Example
Consider the following circuit illustrated in Figure 2 for which we will perform an MCA. The values of the different elements are given: S1=12 V and S2=6 V; R1=15 Ω, R2=2 Ω, and R3=12 Ω.
fig 2: Example of a circuit to perform an MCA on
Step number one has already been done in the circuit where the mesh currents are labeled with the red loop symbols.
As step number 2 suggests, we apply KVL for each mesh of the circuit:
Equation 1: -V1+I1×(R1+R2)-I2×R2=0
Equation 2: V2-I1×R2+I2×(R2+R3)=0
In our case, both mesh currents I1 and I2 are present across the resistor R2, in both equations we can see that the current across R2 is considered as the algebraic sum of I1 and I2.
In the following, we replace the parameters by their value, first of all, we express I1 as a function of I2 thanks to the first equation:
I1=(12+2×I2)/17
We substitute this term in Equation 2, which after redistributing the terms, leads to find I2=-1/3 A. We put this value in the expression of I1 to find I1=2/3 A.
Finally, we can give the required current I to drive the circuit I=I1-I2=1 A.
Conclusion
We have presented in this tutorial two methods based on the Kirchoff’s Circuit Laws called the Nodal Voltage Analysis (NVA) and the Mesh Current Analysis (MCA). These methods are more efficient to analyze circuits because they lead to the solution faster than KCL by reducing the amount of mathematics involved.
Each analysis consists of a series of steps to perform, the methods are presented separately at the beginning of their respective section.
Examples are also given in order to show how to analyze resistive circuits with these two methods. We can note that for reactive circuits with inductors and capacitors, the NVA or MCA analysis leads to a differential equation or a system of differential equations to be solved.
