NAME
Lab::Instrument::Yokogawa7651 - Yokogawa 7651 DC source
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=>0.01Additinally 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 => 1to 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 => 1to 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 => 1to 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
settingThe 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.
