GPIB::hpe3631a - Perl-GPIB module HPE3631A power supply
use GPIB::hpe3631a; $g->GPIB::hpe3631a->new("name"); $g->output(1); # Outputs on $g->output(0); # Outputs off $v = $g->output; # Read output state $g->track(1); # P25V and N25V track voltage $g->track(0); # stop tracking $v = $g->track; # Get tracking state $t = $g->display; $g->display("String"); ($voltage, $current) = $g->measure(P6V) # P6V, P25V, or N25V ($voltage, $current) = $g->get(P6V) # P6V, P25V, or N25V $g->set(P6V, $voltage, $current) # P6V, P25V, or N25V
GPIB::hpe3631a privides control for the HPE3631E bench power supply. This module works with both GPIB and serial interface modules as defined by the /etc/pgpib.conf configuration.
$g->display with no parameter returns the contents of the display. $g->display("string") sets the display to the specified string. Note the the device can only display a limited set of characters, probably best to stick with upper case captions.
$g->measure(P6V) returns a two element list representing the voltage and current at the specified output.
$g->get(P6V) returns a two element list of the voltage and current limits for te specified output.
$g->set(P6V, $v, $c) sets the current limits for the specified output.
A typical /etc/pgpib.conf configuration for a GPIB interface is shown below. The HPE3631A uses primary address 5 by default:
# name interface Board PAD SAD TMO EOT EOS HPE3631A GPIB::ni 0 5 0 T1s 1 0
A typical /etc/pgpib.conf configuration for a serial interface is shown below. The HPE3631A uses 9600 baud by default. The flag value of 0x0001 says to use RTS/CTS hardware flow control. This is pretty much required. The device seems to overflow easily unless hardware flow control is used. Note that the HPE3631A uses DTR/DSR flow control and Linux only supports RTS/CTS flow control so you are pretty much stuck building a custom serial cable.
