Keithley S530 User Manual

S530/S540 KTE Linear Parametric Test Library (LPTLib) User's Manual Section 3:
LPTLib command reference
S530-900-01 Rev. E / September 2017 3-13
bmeasX
This command makes a series of readings as quickly as possible. This measurement mode allows for waveform
capture and analysis (within the resolution of the measurement instrument).
Usage
int bmeasi(int instr_id, double *result, unsigned int numrdg, double delay, int timerid,
double *timerdata);
The bmeasi command has been deprecated. It is listed here for users with older systems.
int bmeasv(int instr_id, double *result, unsigned int numrdg, double delay, int timerid,
double *timerdata);
instr_id
The instrument identification code of the measuring instrument; SMUn, CMTRn,
IMTR
n
, VMTR
n
result
The result name of the array to receive readings; the array must be large enough to
hold the readings
numrdg
The number of readings to return in the array
delay
The delay between points to wait (in seconds)
timerid
The device name of the timer to use (
0
= no timer data)
timerdata
The array used to receive the time points at which the readings were made; if
timerID = 0, the timer is not read and this array is not updated; if used, the array
must be large enough to hold the readings
Details
This command collects data using the presently selected range. The measurement range is typically
the same as the force range. If you need a different range, you must change the measurement range
before calling the bmeasX command.
When used with the time module, the measurements and the times for each measurement are stored.
The specific timer is defined in the command, and the time array is returned with the results array.
Each Series 2600A SourceMeter
®
instrument has a single timer. If you have four Series 2600A
instruments in the S530/S540 system, you can use TIMER1 through TIMER4 for the timerid
parameter. If there are two Series 2600A instruments in the system, you can use TIMER1 and
TIMER2.
Each Series 2600B instrument has eight independent timers, but the S530/S540 supports only four
timers; you can use only TIMER1 through TIMER4 for the timerid parameter.
