Syntax Reply Description
!
Continue operation from a wait condition caused by power on self test
(POST) failure. This is the remote control equivalent of "press any key to
continue".
A*
Enable or disable Automatic Gain Control (AGC) operation. Replace the *
with 1 to enable AGC operation or 0 to disable AGC operation. When
AGC operation is disabled, the current Manual Gain setting is in effect.
A?
Request current status of AGC (on or off).
AK?
AGC attack time report requests the current AGC attack time used with
the fast attack, slow decay AGC used in all modes except AM. The reply
format is the same as for the AGC attack time command above. This
command is only available over the remote control bus.
AKn
AGC attack time command, sets the AGC attack time used with the fast
attack, slow decay AGC (all modes except AM). The character 'n' is
replaced with a digit between 1 and 9. The value 9 gives the original
'normal' attack time, with smaller values reducing the attack time
proportionately. The AGC attack time is not stored in non-volatile
memory. When power is first applied the the unit, the AGC attack time is
set to the normal value, AK9. This command is only available over the
remote control bus.
An
(AGC on/off) is expanded to add the Gain Hold feature. The argument 'n'
is one of the following values:
0 MGC operation, as before
1 AGC operation, as before
2 Reserved
3 Gain Hold mode. Current gain setting is 'frozen'. This
mode is not available when ISB operation is selected
and is only available over the remote control bus.
B±1234
Change BFO offset. The ± character represents the sign of the desired
value, and is replaced with either - or +. The digits 1 through 4 represent
the value of the offset in Hertz with the character 1 representing the 1
kilohertz digit and the 4 representing the Hertz digit. The BFO setting is
only used when the mode is CW. Any changes to the BFO when the
mode is not CW will result in an Unrecognized Command error. (Range: -
6000 to +6000 Hz).
B?
Request current BFO setting.
BI
Perform the built-in-test-equipment (BITE) test sequence. This command
may take several seconds to complete. To see the results of the BITE test,
send the BI? command.
