NAME
Lab::Moose::Instrument::AH2700A - Andeen-Hagerling AH2700A ultra-precision capacitance bridge
VERSION
version 3.920
SYNOPSIS
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
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
set_bias
$AH->set_bias( value = (OFF / IHIGH / ILOW) );
Controls the user-supplied DC bias voltage and selects the
value of an internal resistor placed in series with this
voltage.
OFF: Disabled
ILOW: 100 megaohm resistor
IHIGH: 1 megaohm resistor
|
get_bias
set_cable
get_cable
get_value
($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
