Language
The HP 8648 signal generator can be operated remotely using either
SCPI or HP 8656/57-compatible language. SCPI is the recommended
language for remote programming and all features are supported.
HP 8656/57-compatible language is offered so that the HP 8648
signal generator can be used as a replacement for the HP 8656B
and 8657A/B. The HP 8648 is not fully compatible with programs
developed for the HP 8656/57 but with the following minor changes, it
can be:
w On the HP 8656/57, if the SCPI code turns RF to off and then
changes amplitude, the RF automatically turns back on. For this
same SCPI code to work in the HP 8648, the following line of code
must be added to turn the RF back on: OUTP: STAT ON.
On the HP 8656/57, a line terminator is not required to execute a
line of code. For the HP 8648, however, a new line is required.
Send the SCPI command SYST : LANG “COMP” to change from SCPI to
HP 8656/57-compatible language or change the setting of the rear
panel language switch. The switch is read once at power-up so if
the language has been remotely selected, it will revert to the switch
setting when power is cycled.
