High Frequency Standard Capacitor
GenRad 1403 Series
-
The GenRad 1403 Standard Air Capacitors are stable, three-terminal standards in decimal values from 0.001 pF to 1000 pF. For measurement at 100 pF and below, a three terminal connection increases the accuracy by eliminating the uncertainty in the measurement introduced by the capacitances between the capacitor terminals and ground.

Erbium Fiber Frequency Comb
-
Detailed description of item: The AOSense frequency comb is a low noise, polarization maintaining (PM) device. Key features include a PM fiber architecture centered at 1550nm with turnkey modelocking; a free-running linewidth of the carrier-envelope offset frequency of <200 kHz; a temperature-insensitive all-fiber f-2f interferometer exhibiting fceo beatnotes with SNR > 45dB (300kHz RBW); and dual fast/slow cavity length actuators with a bandwidth of >300 kHz. The repetition rate of the comb is factory set and allows matching across multiple combs for dual comb applications. The optics package incorporates an optical heterodyne module designed for locking to the comb to an ITU-specified laser reference. The comb is capable of supporting an Allan deviation of < 5 x 10-18 at 1 second and ~10-20 after 105 seconds. Add-on features include all fiber extensions to visible wavelengths corresponding to several atomic transitions. An integrated comb electronics package is currently under development.

High Frequency Noise Simulator
SKS-H04GA
-
Shanghai Sanki Electronic Industries Co., Ltd.
The high-frequency noise simulation generator is an EMC test instrument that reproduces high-frequency noise with a fast rise time when the switch is turned on/off. Since the pulse rise time is less than 1ns and contains wide bandwidth noise, it is very suitable for reproducing malfunctions. The line noise entering the power line and the induced noise entering the communication line can be reproduced, and the performance evaluation of the malfunction and function degradation of electronic products can be performed.
