The 4225-PMU or 4220-PGU returns to the following states:
•
The pulse mode is maintained. For example, if the pulse card is in Segment Arb mode, it will still
be in Segment Arb mode after the
devint
process is complete.
•
5 V and 10 mA ranges
•
If in pulse mode:
Period of 1.0
µ
s
Transition Times (Rise and Fall) of 100
n
s
Width of 500
n
s
Voltage high and low of 0 V
Load of 50 Ω
•
If in segmented arb mode, Start Voltage is 0 V
•
If in arbitrary waveform mode, Table Length is 100

dsweepf
This command performs a dual frequency sweep.
Usage
int dsweepf(int
instr_id
, double
startf
, double
stopf
, long *
NumPts
, double
delaytime
);
instr_id
The instrument identification code of the 4210-CVU:
CVU1
startf
Initial frequency for the sweep
stopf
Final frequency for the first sweep
NumPts
Variable to receive the number of points sourced during the sweep
delaytime
Delay before each measurement (0 to 999 s)
Details
Use the
sweepf
command to perform a single frequency sweep.
This command is used to perform a dual frequency sweep (see
Example
). The 4210-CVU provides
test frequencies from 1 kHz to 10 MHz in the following steps:
•
1 kHz through 10 kHz in 1 kHz steps
•
10 kHz to 100 kHz in 10 kHz steps
•
100 kHz to 1 MHz in 100 kHz steps
•
1 MHz to 10 MHz in 1 MHz steps
