Returned values; see
Details
InstIdStr
The CMTR instrument ID;
CMTR1
or
CMTR2
(default), depending on your system
configuration
LoPin
The DUT pin to which the Model 4284A or 4980 low terminal is attached (
−
1 to 72;
default 0); if a value of less than 1 is specified, no switch matrix connection is made;
see
Details
HiPin
The DUT pin to which the Model 4284A or 4980 high terminal is attached (
−
1 to 72;
default 0); if a value of less than 1 is specified, no switch matrix connection is made;
see
Details
SignalLevel
The oscillator output voltage level: 5 mV to 20 V; default 0.045 V
Frequency
Measurement frequency of the sweep: 20 Hz to 1e6 Hz; default 100e3 Hz
BiasV
The DC bias to use for the measurement:
−
40 V to +40 V; default 1.0 V
Range
The measurement range to use (in ohms): 0 (Auto, the default), 100, 300, 1000,
3000, 10000, 30000, or 100000
Model
Measurement model:
Series
or
Parallel
IntegrationTime
The integration time to use:
•
Short:
0
•
Medium:
1
(default)
•
Long:
2
C
Output: The measured capacitance
V
Output: The bias voltage used
G_or_R
Output:
•
Parallel measurement model (
G_or_R
is the measured conductance):
1
•
Series measurement model (
G_or_R
is the measured resistance):
0
Details
This user module makes a single, fixed-bias capacitance and conductance measurement.
If a switch matrix to route signals is being controlled by a connection action UTM (for example,
connect
), there is no need to connect
LoPin
and
HiPin
. Set these parameters to
0
.
Returned values are placed in the Analyze spreadsheet.
•
0
: OK.
•
-10000 (INVAL_INST_ID)
: The specified instrument ID does not exist.
•
-10030 (HP4284_NOT_IN_KCON)
: No Keysight 4284A or Keysight 4980 LCR is defined in your
system configuration.
•
-10031 (HP4284_MEAS_ERROR)
: A measurement error occurred.
