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.

*RST	Reset the Model 2700
:SENSE:FUNCTION 'VOLT:DC'	Set for DCV
:FORMAT:ELEMENT READ	Format statement for readings only
:SYSTEM:AZERO:STATE OFF	Turn off Auto Zero function
:SENSE:VOLT:DC:AVERAGE:STATE OFF	Turn off the filter for DCV
:SENSE:VOLT:DC:NPLC 0.01	Integration rate to 0.01 line cycles
:SENSE:VOLT:DC:RANGE 10	Set fixed range of 10V
:SENSE:VOLT:DC:DIGITS 4	Set resolution to 3 ½ digits
:TRIGGER:COUNT 1	Set trigger count to 1
:SAMPLE:COUNT 1000	Set sample count 1000
:TRIGGER:DELAY 0.0	Set trigger delay to zero
:DISPLAY:ENABLE OFF	Turn off the display
:READ?	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.
