Model 4200-SCS Reference Manual
Y2 axis maximum value
±DDDD.DDD
Example
The command string:
YB 'I2', 2, 100E-9, 1E-3
does the following:
Measurement control page (MD)
In order to send the command string to control measurements, the measurement control page
must first be selected by sending the following command:
MD
ME command: Control measurements
There are four command strings to control measurements. The ME1 or ME2 command will trigger
the start of the test and perform the programmed number of measurements. The measured
readings are stored in the buffer. Note that the buffer is cleared before readings are stored.
The ME3 command also triggers the test but does not clear the buffer before storing the measured
readings. The readings are appended to the readings already stored in the buffer. The buffer can
hold up to 4096 readings.
The ME4 command aborts the test.

Example
The following command string triggers the start of the test and stores the readings in the cleared
buffer:
