Programming Basics
Programming Tips
To Use the Internal Program Memory
If your program repeats the setup and measurement for a number of devices, use the
internal program memory. For these measurements, using the internal program
memory reduces the command transfer time, and improves the program execution
speed.
You can enter a maximum of 2,000 programs (total 40,000 commands) into the
internal program memory. Refer to
Chapter 2, “Remote Mode Functions.”
To Get Time Data with the Best Resolution
To read the time data with the best resolution (100 μs), the timer must be cleared
within the following interval:
•100 sec or less (for FMT1, 2, or 5 data output format)
• 1000 sec or less (for FMT 11, 12, 15, 21, 22, or 25 data output format)
Send the TSR command to clear the timer.
To Use Sweep Source as a Constant Source
The following setup enables sweep source to force a constant current or voltage.
• Sweep start value = Sweep stop value (for WI, WV, or WNX).
Also, setting number of sweep steps to 1 enables to perform a spot measurement.
To Start Measurements Simultaneously
Spot measurement, staircase sweep measurement, and multi channel sweep
measurement enable to use multiple measurement channels. Then the measurement
channels perform measurement in the order defined in the MM command. However,
the measurement channels with the following setup start measurements
simultaneously.
• To set the multi channel sweep measurement mode (MM 16).
• To set the measurement ranging mode to fixed (for RI or RV).
• For the Keysight E5270B, to use the high-speed ADC (use AV).
NOTE Measurement setup is independent from source output setup. So, this simultaneous
measurement cannot be broken by the source output setup. Any setting of the output
ranging mode is effective for the simultaneous measurement.
