Ctsweep590 User Module - Keithley 4200A-SCS Reference Manual

Model 4200A-SCS Parameter Analyzer Reference Manual
Procedure
1. You are prompted to open the circuit so that an offset capacitance measurement can be made, if
needed.
2. If a cable compensation file is specified, the compensation information in that file for the selected
range and frequency is loaded. If not, instrument default compensation is used.
3. The capacitance and conductance are measured.

CtSweep590 user module

The CtSweep590 routine performs a capacitance versus time (C
Analyzer. You can make an offset correction measurement and use cable compensation.

The CMTR instrument ID; CMTR1, CMTR2, CMTR3, or CMTR4, depending on your
system configuration
The DUT pin to which the 590 input terminal is attached (−1 to 72); if a value of less
than 1 is specified, no switch matrix connection is made; see Details
The DUT pin to which the 590 output terminal is attached (−1 to 72); if a value of
less than 1 is specified, no switch matrix connection is made; see Details
Determines if an offset correction measurement should be made:
•
Do not make offset measurement: 0
•
Make offset measurement: 1
The measurement frequency to use:
•
100 kHz: 0
•
1 MHz: 1
The DC bias to use for the measurement: −20 V to +20 V
The DC bias that is applied during a sweep: −20 V to +20 V
The time that occurs on the first bias step, from the point the instrument is first
triggered until the first step time: 0.001 s to 65 s
The time period after a transition to a new bias step and before the instrument
begins a measurement: 0.001 s to 65 s
The measurement range to use in F: 2E-12, 20E-12, 200E-12, or 2E-9; see Details
Measurement model:
•
Series model: 0
•
Parallel model: 1
Enable or disable the analog filter, which can minimize the amount of noise that
appears in the readings; however, it increases the measurement time:
•
Disable the filter: 0
•
Enable the filter: 1
The number of readings per sweep: 1 to 1350
Selects the reading rate used to acquire the measurements: 0 to 4; see Details
