Classic Test Definition
Direct Control
ReadDataBuffer
This function reads the measurement data. The number of data blocks to be read is
specified by the count parameter. If count is abbreviated, this function reads one
data block.
Syntax
ReadDataBuffer [count]
Parameters count Number of data blocks or the number of terminators to be read.
A data block is a group of data that ends with a terminator. For
the data ou
tput format, see “Agilent B1500A Programming
Guide”.
Example The following example performs three hig
h speed s
pot measurements and then
reads three measurement data blocks.
NOTE The data output buffer is cleared when the Direct Control test is started.
NOTE If a SMU performs the force side measurement operation and the source data output
is enabled (by the FMT command), the SMU’s source data is deleted and the SMU’s
measurement data is stored instead of the source data. The force side measurement
operation is the SMU operation which performs the voltage force and voltage
measurement or the current force and current measurement.
Command Arguments Description
TI 1, 0 Measurement channel 1 performs the high
speed spot meas
urement.
TI 2, 0 Measurement channel 2 performs the high
speed spot meas
urement.
TI 3, 0 Measurement channel 3 performs the high
speed spot meas
urement.
ReadDataBuffer 3 Reads three measurement data blocks.
