242 Agilent N5181A/82A MXG Signal Generators SCPI Command Reference
SCPI Compatibility
8656B, 8657A/B/D/J Programming Codes
• If AM or pulse modulation is on, the signal generator attempts to set up FM with the same
settings and turns off the other modulation.
S4 (Modulation Source Off)
• If PM is the current active function, pulse modulation is disabled by mapping to the following
command:
[:SOURce]:PULM:STATe OFF
• If the last code executed is S2 or S3, internal modulation is turned off for the AM and FM:
[:SOURce]:AM[1]:STATe OFF
[:SOURce]:FM[1]:STATe OFF
• If the last code executed is S1, external modulation is turned off for the AM and FM:
[:SOURce]:AM[1]:STATe OFF
[:SOURce]:FM[1]:STATe OFF
• If the current active function is AM or FM, the appropriate modulation is turned off:
[:SOURce]:AM[1]:STATe OFF
[:SOURce]:FM[1]:STATe OFF
• If S4 is executed with S1, S2, or S3, it will turn off the current modulation.
S5 (DC FM)
• FM becomes the active function.
• In addition, the following commands are mapped:
[:SOURce]:FM[1]:SOURce EXTernal1
[:SOURce]:PULM:STATe OFF
[:SOURce]:AM[1]:STATe OFF
[:SOURce]:FM[1]:EXTernal[1]:COUPling DC
[:SOURce]:FM[1]:STATe ON
