NAME

hp8656 - control HP 8656A signal generator

SYNOPSIS

hp8656 [OPTIONS]

DESCRIPTION

hp8656 controls the HP 8656A signal generator via its GPIB interface.

hp8656 performs actions selected on the command line in a fixed sequence:

clear
configure
local

If an action is not selected on the command line, it is not peformed.

OPTIONS

hp8656 accepts the following command line options:

-a, --address address

Override the default instrument address in /etc/gpib-utils.conf.

-c, --clear

Clear the instrument and load the following defaults:

carrier frequency: 100 MHz
carrier amplitude: -127.0dBm
carrier frequency increment: 10 Mhz
carrier amplitude increment: 10 dB
AM depth: 0%
AM depth increment: 1%;
FM peak deviation frequency: 0.0 kHz
FM peak deviation frequency increment: 1.0 kHz
coarse and fine tune pointer: 10 MHz
sequence counter: 0

-l, --local

Enable front panel.

-f, --frequency value

Set the carrier frequency. A value of ``up'' or ``down'' adjust the current frequency by the carrier frequency increment.

-A, --amplitude value

Set the carrier amplitude. A value of ``up'' or ``down'' adjust the current amplitude by the carrier amplitude increment.

-F, --incrfreq value

Set the carrier frequency increment.

-i, --incrampl value

Set the carrier amplitude increment.

EXAMPLES

Configure the instrument to generate a 100 kHz carrier with 1v amplitude, then step the frequency to 1 Mhz in 10 kHz increments.

hp8656 --clear --frequency 100khz --incrfreq 10khz --amplitude 1v
for freq in `seq 100 10 1000`; do
   hp8656 --frequency up
done
hp8656 --local
