, where x is the new value of the phone output gain.
If this command was issued after the example
above, then the status message would be .
8.127. SGGAIN -- Set Gain of Signal Generator
This command sets the gain of the internal signal generator. The value of SGGAIN specifies the gain in dB
applied to signal generator. A gain of 0 dB produces a signal at nominal level (-20 dB full scale).
This command is an integer command. See
Section 6.2 for more information on this type of command. The
minimum and maximum values for this command are -100 and 20, respectively.
This command is saved to non-volatile memory only as part of a preset. The state of this command will be
restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
Example Description Status Message
F01SGGAIN6
Set signal generator gain to 6 dB.
F01SGGAIN6
F01SGGAIN>3
Increase signal generator gain by 3 dB.
F01SGGAINx , where x is the new value of the signal
generator gain. If this command was issued after the
example above, then the status message would be
F01SGGAIN9 .
F01SGGAIN?
Query signal generator gain.
F01SGGAINx , where x is the new value of the signal
generator gain. If this command was issued after the
example above, then the status message would be
F01SGGAIN9 .
8.128. SGMUTE -- Mute Signal Generator
This command controls the muting of the signal generator.
This command is a boolean command. See
Section 6.1 for more information on this type of command.
This command is saved to non-volatile memory only as part of a preset. The state of this command will be
restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
