How to Read a Power MOSFET Datasheet.

Read the fine print!  For example, the IRFP260N’s RDS(on) has a maximum of 0.04 Ω at VGS = 10V, ID = 28A at a junction temperature of 25°C: this is an assertion, a claim. It is NOT a warranty or guarantee unless the manufacturer says so …

AMAZING! New PicoScope 6000E Series 8-ch 500MHz Oscilloscopes

AMAZING! New PicoScope 6000E Series 8-ch 500MHz Oscilloscopes provide 8 to 12 bits of vertical resolution, 5GSa/s sampling rate, and 4GSa memory, plus 8 or 16 optional digital channels, and can provide with an extra 4 bits of resolution with the enhanced vertical resolution software feature.   https://youtu.be/t7qcWYmk-K0

 The two models in the 6000 series are the PicoScope 6804E with 8-bit A/D resolution and the PicoScope 6824E with 8, 10, or 12 bits “FlexRes” resolution. Both models can operate with an extra 4 bits of resolution with the enhanced vertical resolution software feature — a digital signal processing technique built into PicoScope 6. These oscilloscopes offer 8 analog channels, plus 8 or 16 optional digital channels when using the plug-in TA369 MSO pods, enabling accurate time-correlation of analog and digital channels.  

Both 6000E models include a 14-bit 200MS/s arbitrary waveform generator (AWG). Its variable sample clock avoids the jitter on waveform edges seen with fixed-clock generators and allows generation of accurate frequencies down to 100μHz. AWG waveforms can be created or edited using the built-in editor, imported from oscilloscope traces, loaded from a spreadsheet or exported to a .csv file.  The SuperSpeed USB 3.0 interface and hardware acceleration ensure that the display is smooth and responsive even with long captures.  PicoScope 6 software includes decoders for many serial protocols.

This unique picocurrent logger measures miniscule bipolar current

Saelig Company, Inc. announces the availability of the RBD 9103 USB Graphing Picoammeter, a compact, versatile, general-purpose picoammeter designed to accurately measure DC current from nanoamps to milliamps via its isolated BNC input. This rugged, portable, and affordable picocurrent sensor is available with high-speed and high-voltage options, optional bias, and 5kVDC float isolation. The 9103 USB Picoammeter measures bi-polar DC current and can be biased from an optional built-in fixed +90VDC bias, or an external low-noise DC power supply. It comes with a  NIST-traceable calibration certificate.

The 9103 can take accurate current measurementsfrom 1pA to 2.499mA at sample rates up to 500Sa/s. The user-friendly PC software interface supplied provides optimal control and quick access to all functions such as data recording and graphing. The 9103 is also compatible with OSx, Linux, Matlab, and LabView, and can be controlled via a simple ASCII interface.

The 9103 is available in four models:

• Standard: sample rate 40Sa/s and optional 90 V fixed or external bias.
• High-speed: sample rate 500Sa/s and optional 90 V fixed or external bias.
• High-voltage: sample rate 40Sa/s, isolated input can float up to 5kVDC
• High-speed / High-Voltage: sample rate 500Sa/s, floats up to 5 kV DC

Designed to provide precise bipolar DC current measurements even in noisy environments such as synchrotron beam lines, the 9103 is equally suited for diode and IC I/V characterization. With unique qualities like DC voltage isolation from chassis ground to 5kV, possibilities for researchers include direct DC current measurement of very small electron and photo multiplier signals.  Electron and ion beam measurements can be biased to reduce secondary electrons or to retard the beam as needed for experiments. The 9103 is also multi-channel capable - up to 127 units can be synchronized together.

Saelig's Tech Support Manager tests the shielding effectiveness of this forensic EMI enclosure

For nearly two decades, the patented Ramsey STE3000 series RF Test Enclosure has been the wireless industry standard for a benchtop RF test chamber that provide both visual and hands-access to the device under test. As the term “cellular forensics” entered all of our vocabulary, it was natural that we also became the standard for that industry. The STE3000F2 was designed to give the forensics technician the equivalent of a highly isolated screen room right on his bench to perform electronic device interrogations.
