IsoVu -
Tektronix, Inc.
IsoVu offers complete galvanic isolation and is the industry’s first measurement solution capable of accurately resolving high bandwidth, low voltage differential signals in the presence of large common mode voltages. The stand out feature of IsoVu™ is its best in class common mode rejection across the entire bandwidth. Accurate differential measurements rely on a measurement system’s bandwidth, rise time, common mode voltage, common mode rejection capability, and the ability to connect to smaller test points to characterize devices that are shrinking in size and increasing in performance. Despite these requirements, advancements in test and measurement for power testing, EMI testing, ESD testing, and remote measurement capability have been minimal at best and have not kept pace with changing requirements. While differential voltage probes have had modest performance gains in regard to bandwidth, these probes have failed to make any substantial improvements in regard to common mode rejection, and connectivity. IsoVu is a leap forward in technology and is the only solution with the required combination of high bandwidth, high common mode voltage, and high common mode rejection to enable these differential measurements.

PI-41702 -
Pulse Instruments
The PI-41702 is a four channel bipolar DC Bias supply that can provide an output current up to 100 mA per channel. The output voltage ranges from –8 V to +8 V, and this card has special filter circuitry to reduce the output noise for those applications that require a low noise bias output. Additionally there is a ‘D’ type connector that allows the introduction of laboratory type supplies to reduce the noise further. To change from using the internal power supplies to external power supplies requires repositioning jumpers. The PI-41702 also has voltage and current sense for remote measurement of the voltage and current levels.

Shanghai Guantu Technology Co., Ltd.
How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.
