Remote Operation: What SCPI Commands Maximize the Measurement Speed of my Integra Mainframe?
Product(s) : 2700, 2701 and 2750
Question : How can the Integra Series be configured for maximum measurement speed?
Answer: The maximum measurement speed of an Integra Series mainframe is:
Model Speed 2700 2000 rdgs/sec 2750 2500 rdgs/sec 2701 3500 rdgs/sec
Maximum speed is achieved by remote programming through RS-232 or GPIB or ethernet in the case of the 2701. The data is stored in the mainframe's scratch pad memory using the :READ? command. This is used instead of the TRACE buffer for absolute maximum speed. Use the following commands to configure for maximum speed.
Reset the Model 2700
Set for DCV
Format statement for readings only
Turn off Auto Zero function
Turn off the filter for DCV
Integration rate to 0.01 line cycles
Set fixed range of 10V
Set resolution to 3 Â½ digits
Set trigger count to 1
Set sample count 1000
Set trigger delay to zero
Turn off the display
Send the :READ? Command
Your Code to Read the data
These are the basic commands to setup the Integra mainframe for maximum measurement speed. This command set configuration does not include any scanning time nor the time required to transfer the data across the bus. This is just the measurement speed and storage into an internal buffer. Use of switching modules would introduce additional overhead and reduce the overall throughput.
To verify the performance, apply a 1 Hz sine wave to the front voltage terminals. Acquire a buffer equal in size to the maximum reading rate for your particular model of instrument, e.g., 2500 readings for Model 2750. When the data are returned to your program, they will comprise one full cycle of the applied waveform.
