NAME

Lab::Moose::Instrument::AH2700A - Andeen-Hagerling AH2700A ultra-precision capacitance bridge

VERSION

version 3.901

SYNOPSIS

 use Lab::Moose;

 # Constructor
 my $AH = instrument(
     type            => 'AH2700A',
     connection_type => 'VISA_GPIB',
     connection_options => {
         pad => 28,
     },
 );

METHODS

set_frq

 $AH->set_frq( value => (50..20000) );

 The frequency can be chosen between 50 Hz and 20 kHz.
 Since the AH2700A is a discrete frequency bridge it will select
 the nearest supported frequency when entering a value.

get_frq

 $AH->get_frq();

set_aver

 $AH->set_aver( value => (0..15) );

 Sets the approximate time used to make a measurement.
 This command sets the "average time exponent" controlling
 the measurement times for cold and warm-start measurements.

 The actual time taken can be calculated using the table from
 the manual on this function.

get_aver

 $AH->get_aver();

set_bias

 $AH->set_bias( value = (OFF / IHIGH / ILOW) );

 Controls the user-supplied DC bias voltage and selects the
 value of an internal resistor placed in series with this
 voltage.

 OFF:   Disabled
 ILOW:  100 megaohm resistor
 IHIGH: 1 megaohm resistor

get_bias

 $AH->get_bias();

set_cable

get_cable

get_value

 ($frequency, $capacity, $loss) = $AH->get_value();

 Causes the bridge to take a single measurement.

set_wait

set_field

 $AH->set_field(fi1 => "OFF", fi2 => "OFF", fi3 => 9, fi4 => 9, fi5 => "ON", fi6 => "OFF");

 Controls the fields sent and the number of significant digits
 reported for capacitance and/or loss measurements.

 fi1: send the sample field ON/OFF
 fi2: send the frequency field ON/OFF
 fi3: send the capacitance field and control number of digits
      0..9
 fi4: send the loss field and control number of digits
      0..9
 fi5: send the voltage field ON/OFF
 fi6: send the error field ON/OFF

set_volt
