NAME

Lab::Instrument::Yokogawa7651 - Yokogawa 7651 DC source

VERSION

version 3.830

SYNOPSIS

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();

DESCRIPTION

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.

CONSTRUCTORS

new( %configuration_HASH )

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.

METHODS

set_voltage

$src->set_voltage($voltage)

Sets the output voltage to $voltage. Returns the newly set voltage.

get_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.

set_current

$src->set_current($current)

Sets the output current to $current. Returns the newly set current.

get_current

Returns the currently set $current. The value is read from the driver cache by default. Provide the option

device_cache => 1

to read directly from the device.

set_level

$src->set_level($lvl)

Sets the level $lvl in the current operation mode.

get_level

$lvl = $src->get_level()

Returns the currently set level. Use

device_cache => 1

to enforce a reading directly from the device.

sweep_to_level

$src->sweep_to_level($lvl,$time)

Sweep to the level $lvl in $time seconds.

set_range

$src->set_range($range)

Set the output range for the device. $range should be either in decimal or scientific notation. Returns the newly set range.

get_info

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.

set_output

$src->set_output( $onoff )

Sets the output switch to "1" (on) or "0" (off). Returns the new output state;

get_output

Returns the status of the output switch (0 or 1).

set_voltage_limit($limit)

set_current_limit($limit)

get_status()

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.

INSTRUMENT SPECIFICATIONS

DC voltage

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.
