Automation
50 Hz Adaptive Filter
One of the main causes of the reduction of accuracy in low frequency signal parameters measurements is the influence of artificial and natural electromagnetic interferences on measuring channels of measuring tools (MT). Under laboratory, production and natural conditions, the main interference is 50 Hz network interference. To eliminate this interference, ZETLAB software package uses a program providing a 50 Hz band-stop filter.

Dust Caps, Opens
These coaxial dust caps are used for protective purposes, both from the environment & contaminants. Note: SMA, 2.92, 3.5mm dust caps are the same, as the threads are the same. Likewise, 2.4mm & 1.85mm dust caps are the same, the threads being the same. Some people use opens for calibration purposes at low frequencies, but these opens are not VNA rated, we don't measure fringing capacitance etc.

÷10, 500 MHz, 10 MΩ, Passive Probe (Total of 1 Per Channel)
PP008-1
Passive probes are the standard probe provided with most oscilloscopes. Typical passive probes provide a 10:1 attenuation and feature a high input resistance of 10 MΩ. This high input resistance means that passive probes are the ideal tool for low frequency signals since circuit loading at these frequencies is minimized. Passive probes are designed to handle voltages of at least 400V, some as high as 600V. Teledyne LeCroy passive probes feature an attenuation sense pin which tells the oscilloscope to scale the waveforms automatically requiring no user input.Each passive probe is recommended for a certain oscilloscope, using the right passive probe with the right oscilloscope means that the probe will be properly compensated across the entire bandwidth. Using probes with a different oscilloscope will only let you compensate for low frequencies.

High Voltage Switching Test System
The advanced development of new technologies, such as SiC and GaN, have opened the opportunity for more efficient and higher voltage/power performance in switching and power management circuits. Their high cutoff frequencies, low on-state resistance, and very high breakdown voltages can increase power supply power handling densities approaching hundreds of watts/inch. Reliability of these new technologies and techniques is critical for realizing practical applications. While Silicon devices have a rich history of proven reliability, these newer compound semiconductor technologies are too new to have a reliability history and have not been well proven. Further, process variations, even in well-controlled lines, yield widely varying results. This has driven the need for additional testing and to burn-in devices prior to delivery.
