Procedure 3. 8350B/Plug-ins Front Panel FREQ CAL

Procedure 3. 8350B/Plug-ins Front Panel FREQ CAL
1. Press 8350B
INSTR PRESET, CW, 50, MHz
2. Connect the external frequency counter through a 10 dB attenuator to the
RF OUTPUT.
3. Adjust the FREQ CAL control for a frequency counter indication of 50.0 MHz.

Alternate Procedure

This alternate FREQ CAL procedure is not as accurate as using an external counter, but
normally calibrates the Band 0 frequency accuracy within specifications.
1. Press 8350B
INSTR PRESET, CW, 0, MHz
2. Adjust the FREQ CAL control through its range and note the portion of its range where
the UNLEVELD light is turned on.
3. Set the FREQ CAL control to the center of this lighted range.

Procedure 4. 8360 Series Sources Full User CAL

Full User Cal initiates a full synthesizer calibration. The calibration performed is
instrument state dependent. For example, if the synthesizer is in ramp sweep mode, a
sweep span and an auto track calibration are done. if the synthesizer has amplitude
modulation active on an SW signal, then RF peaking and AM bandwidth calibrations are
performed. For 8510C purposes only, ramp sweep mode is needed. Perform the following
calibration procedure:
1. On the 8360, press
2. Select
[Full User CAL]

Attenuation Needed

If your 8360 Series source does not have a built-in attenuator, you are prompted to connect
a 10 dB attenuator to the RF output port of the 8360. Auto track is done as part of Full
User Cal.
