NAME

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

SYNOPSIS

use Lab::Instrument::Yokogawa7651;

my $gate14=new Lab::Instrument::Yokogawa7651(0,11);
$gate14->set_range(5);
$gate14->set_voltage(0.745);
print $gate14->get_voltage();

DESCRIPTION

The Lab::Instrument::Yokogawa7651 class implements an interface to the 7651 voltage and current source by Yokogawa. This class derives from Lab::Instrument::Source and provides all functionality described there.

CONSTRUCTORS

new($gpib_board,$gpib_addr)

METHODS

set_voltage($voltage)

get_voltage()

set_range($range)

Fixed voltage mode
    2   10mV
    3   100mV
    4   1V
    5   10V
    6   30V

Fixed current mode
    4   1mA
    5   10mA
    6   100mA

get_info()

Returns the information provided by the instrument's 'OS' command.

output_on()

Sets the output switch to on.

output_off()

Sets the output switch to off. The instrument outputs no voltage or current then, no matter what voltage you set.

get_output()

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

initialize()

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.
