Softkey/Command Cross-Reference ESG Family Signal Generators
Agilent 8656/57-Compatible Language
P4 (Digital Modulation On)
This command turns on digital modulation (for 8657D/J-compatibility only.)
The P4 command is mapped to the following SCPI commands:
[:SOURce]:AM[1]:STATe OFF
[:SOURce]:AM2:STATe OFF
[:SOURce]:FM[1]:STATe OFF
[:SOURce]:FM2:STATe OFF
[:SOURce]:DM:SOURce INTernal1
[:SOURce]:RADIO:<format>:STATe ON
[:SOURce]:RADIO:<format>:REPeat CONT
[:SOURce]:RADIO:<format>:DATA EXTernal
[:SOURce]:DM:STATe ON
where <format> is either NADC, PDC, or PHS, depending on the specific compatibility
language selected.
PF (Pulse Modulation - Fast Mode) or PM (Pulse Modulation)
The ESG Family Signal Generators support only one input for pulse: EXTernal2. (This is a
DC-coupled input.) Internal pulse modulation, therefore, is not supported in
8656/57-compatibility mode. The PF (or PM) command is mapped to the following SCPI
commands:
[:SOURce]:PULM:SOURce EXTernal2
[:SOURce]:PULM:STATe ON
S1 (External Modulation Source)
No action is taken until a modulation form is selected. Pulse is set to EXTernal2. AM and
FM are set to EXTernal1.
S2 (Internal 400 Hz Modulation Source)
If AM1 is on, this command is mapped to:
[:SOURce]:AM[1]:INTernal[1]:FREQuency 400 Hz
If FM1 is on, this command is mapped to:
[:SOURce]:FM1]:INTernal[1]:FREQuency 400 Hz
