This test will measure the Quasi-Peak detector’s response to varying PRFs. The Quasi-Peak Detector has a specific rise and fall response defined in CISPR 16-1-1 (Section 5.2.2). The Quasi-Peak Detector is intended to emulate the response of a mechanical meter’s response to an impulsive signal.
In this test, DC Pulse is applied to the EMI receiver. The DUT is tuned to a frequency within the band of interest. The DUT is placed in zero span, and the sweep time is set to capture at least 1 pulse during a sweep. The pulse generator is set to the reference PRF and the reference amplitude is then measured. Next, the PRF is varied and subsequent amplitude measurements are performed. The amplitudes are normalized to the reference amplitude and compared to the CISPR specification.
You may get a GPIB connection error when using the IGUU 2918.
There is a known issue with certain versions of the Keysight IO Library not recognizing the Schwarzbeck IGUU 2918 pulse generator and therefore causing a GPIB connection failure. There are two work-around methods to correct this error. Refer to the Connecting GPIB Instruments section of Getting Started for more information.
