Status
Command / Function / Remark / Limitation
HI
Unknown function ...
LO
Unknown function ...
UP
Increment the value of the active function (frequency, amplitude, modulation depth,
modulation deviation) by the value specified at command IS.
DN
Decrement the value of the active function (frequency, amplitude, modulation depth,
modulation deviation) by the value specified at command IS.
IS value
Set increment/decrement value of the active function (frequency, amplitude,
modulation depth, modulation deviation).
Value (frequency function):
value in HZ | KZ | MZ
Value (amplitude function):
value in DB
Value (AM):
value in PCT | %
Value (FM):
value in HZ | KZ | MZ
Remark:
% is not supported
PI
Increment RF frequency phase by 1.0 °.
Remark:
No wrap around occurs at the phase limits in opposition to the HP8657.
PD
Decrement RF frequency phase by 1.0 °.
Remark:
No wrap around occurs at the phase limits in opposition to the HP8657.
R0
Select Standby mode.
Remark:
The implementation on SM* is identical to R2.
R1
Select Active mode.
Remark:
The implementation on SM* is identical to R3.
