Yo Delay Compensation, A54 - HP 8340B Manual

5-10. YO DELAY COMPENSATION, A54

Reference
Performance Test: Swept Frequency Accuracy
Service Section: Sweep Generator
Description
In this procedure, the programmable width of the YO kick pulse is calibrated. Then the YO delay is
adjusted so the marker position tracks from the slowest to the fastest sweep speeds.
Equipment
Spectrum Analyzer
Oscilloscope
Adapter, APC-3.5 (f) to Type N
(2 required for HP 8341 B, one for HP 8340B)
Cable, SMA
Adapter, APC 3.5 (f) to APC 3.5 (f) (required for HP 8340B)
In the test setup, 2 APC 3.5 (f) to Type N (in) adapters are used with an
SMA semi-rigid cable. This setup is used, instead of connecting the DUT
to the spectrum analyzer with a Type N cable, to reduce power loss
through the cable.
