Low Noise Prepolarized Microphone
378A04
-
The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.

RF Electronic Calibration Module (ECal), DC/300 KHz To 9 GHz, 4.3-10, 2 Port
85094D
-
The Keysight 85094D RF electronic calibration (ECal) module makes the calibration of vector network analyzers fast, easy, and accurate. ECal is a precision, single-connection calibration technique for your vector network analyzer. Performing a full two-port calibration takes less than half the time and a number of connections using ECal versus mechanical calibration kits. Furthermore, the accuracy of the calibration is comparable between electronic and mechanical methods. Traditional mechanical calibrations require intensive operator interaction, which is prone to errors. With ECal, the operator simply connects the ECal module to the network analyzer and the software controls the rest.

Time to Amplitude Converters and Calibrator
-
A Time-to-Amplitude Converter (TAC) can achieve exceptional precision by using an analog technique to convert small time intervals to pulse amplitudes. When a timing application demands picosecond precision, a time-to-amplitude converter is a prime candidate. A time-to-amplitude converter is a productive solution for measurements less than 10 μs when time resolutions from 10 ps to 50 ns are required.
