This step calibrates the scalar measurements personality for measuring transmission through a filter. 1. Connect a short, low-loss cable between the input and output
l l
If you are using the HP 85630A, connect between Port 1 and Port 2. If you are using a spectrum analyzer, connect between RF OUT and INPUT.
2. Press @?ZGKiWJ, and set the center frequency. Our example is 50 MHz. 3. Press ISPANJ, and set the spanwidth. Our example is 50 MHz. 4. Press the ICAL) key and then the CAL THRU softkey. This enters a guided calibration routine. This routine normalizes the system response thus eliminating system errors from any measurements. 5. Press the STORE THRU softkey.
