PI-41701 - Pulse Instruments

The PI-41701 is a dual 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 features programmable current limits with LED indicators and software interrupt to show/alert the user if the channel is in current limit. This card has special filter circuitry to reduce the output noise for those applications that require a low noise bias output.

DC1000A - Voltech

To guarantee the quality and performance of inductive components such as inductors, chokes and transformers they are tested at their real-life operating point. If the inductor is designed to carry a DC current, then its inductance must be measured with that DC current present. Until now, these measurements were made by an LCR meter connected via special interfacing to a DC bias supply available only from the manufacturer of the LCR meter. The unique NEW DC1000A can be used with any precision LCR meter and connects simply into existing test fixturing.

MKS Ophir

MKS Ophir

The IS1.5-VIS-FPD-800 & IS1.5-IRG-FPD-800 contain 2 photodiodes: a calibrated photodiode for precise power measurement using Ophir meters and a fast photodiode with integral reverse bias circuit for temporal characterization using third-party instrumentation such as oscilloscopes and spectrum analyzers. Their small, 1.5" internal diameter preserves the temporal shape of pulses down to 3.5 nsec for VIS and 6 nsec for IRG. An SMA fiber optic connector is provided for connection to a spectrometer. The large, 20 mm input aperture allows for wide acceptance angles and long working distances, making these spheres well suited for testing VCSELs and other types of laser.

Maury Microwave Corporation

Maury Microwave Corporation

Maury’s line of diplexers (DP-series) and triplexers (TP-series) are designed for applications which require combining/ splitting signals at or around harmonic frequencies (nFo) and are connectorized for design-in and test and measurement applications.DP-series diplexers are designed using low-pass and high-pass filters and pass bias between the low-frequency (or Fo) port and the common (or DUT) port.TP-series triplexers are designed using low-pass, bandpass and high-pass filters and pass bias between the low-frequency (or Fo) port and the common (or DUT) port.Power handling is rated at 100W CW (average) and typical insertion loss is better than 0.5dB between the low-pass (Fo) and common ports.DP- and TP-series multiplexers are ideal accessories for passive, active and hybrid-active multi-harmonic load pull systems.

PIN Photodiode

Appointech, Inc.

Appointech, Inc.

PIN photodiode is a kind of photo detector, it can convert optical signals into electrical signals.This technology was invented in the latest of 1950's. There are three regions in this type of diode. There is a p-region an intrinsic region and an n-region. The p-region and n-region are comparatively heavily doped than the p-region and n-region of usual p-n diodes. The width of the intrinsic region should be larger than the space charge width of a normal p-n junction. The PIN photo diode operates with an applied reverse bias voltage and when the reverse bias is applied, the space charge region must cover the intrinsic region completely. Electron hole pairs are generated in the space charge region by photon absorption. The switching speed of frequency response of photo diode is inversely proportional to the life time. The switching speed can be enhanced by a small minority carrier lifetime. For the photo detector applications where the speed of response is important, the depletion region width should be made as large as possible for small minority carrier lifetime as a result the switch speed also increases.
