Lab::Instrument::Yokogawa7651 - Yokogawa 7651 DC source
use Lab::Instrument::Yokogawa7651; my $gate14=new Lab::Instrument::Yokogawa7651( connection_type => 'LinuxGPIB', gpib_address => 22, gate_protecet => 1, level => 0.5, ); $gate14->set_voltage(0.745); print $gate14->get_voltage();
The Lab::Instrument::Yokogawa7651 class implements an interface to the discontinued voltage and current source 7651 by Yokogawa. This class derives from Lab::Instrument::Source and provides all functionality described there.
HASH is a list of tuples given in the format
key => value,
please supply at least the configuration for the connection: connection_type => "LinxGPIB" gpib_address =>
you might also want to have gate protect from the start (the default values are given):
gate_protect => 1, gp_equal_level => 1e-5, gp_max_units_per_second => 0.05, gp_max_units_per_step => 0.005, gp_max_step_per_second => 10, gp_max_units_per_second => 0.05, gp_max_units_per_step => 0.005, max_sweep_time=>3600, min_sweep_time=>0.1,
If you want to use the sweep function without using gate protect, you should specify
stepsize=>0.01
Additinally there is support to set parameters for the device "on init":
function => Voltage, # specify "Voltage" or "Current" mode, string is case insensitive range => undef, level => undef, output => undef,
If those values are not specified, the current device configuration is left unaltered.
$src->set_voltage($voltage)
Sets the output voltage to $voltage. Returns the newly set voltage.
Returns the currently set $voltage. The value is read from the driver cache by default. Provide the option
device_cache => 1
to read directly from the device.
$src->set_current($current)
Sets the output current to $current. Returns the newly set current.
Returns the currently set $current. The value is read from the driver cache by default. Provide the option
$src->set_level($lvl)
Sets the level $lvl in the current operation mode.
$lvl = $src->get_level()
Returns the currently set level. Use
to enforce a reading directly from the device.
$src->sweep_to_level($lvl,$time)
Sweep to the level $lvl in $time seconds.
$src->set_range($range)
Set the output range for the device. $range should be either in decimal or scientific notation. Returns the newly set range.
Returns the information provided by the instrument's 'OS' command, in the form of an array with one entry per line. For display, use join(',',$yoko->get_info()); or similar.
$src->set_output( $onoff )
Sets the output switch to "1" (on) or "0" (off). Returns the new output state;
Returns the status of the output switch (0 or 1).
Returns a hash with the following keys:
CAL_switch memory_card calibration_mode output unstable error execution setting
The value for each key is either 0 or 1, indicating the status of the instrument.
The stability (24h) is the value at 23 +- 1°C. The stability (90days), accuracy (90days) and accuracy (1year) are values at 23 +- 5°C. The temperature coefficient is the value at 5 to 18°C and 28 to 40°C.
