|27xxMaxSpeedBenchMark.pdf|| Benchmarking the Reading Rate of an Integra Mainframe: Model 2700, 2701 or 2750
The DC Measurement Speeds specifications for the Integra mainframes are defined as the rate at
which data can be acquired and put into a memory buffer. In order for your application to have
this data for analysis, additional time is required to transfer the data across the bus (GPIB, RS-
232 or Ethernet).
In order to verify the speed specification, analysis of the data returned when applying a signal of
known frequency is required. If a 1 Hz waveform is applied and a buffer of data equal in size to
the maximum rate is acquired, then the data in the buffer should represent 1 second or 1 full
cycle of the applied waveform.
Below is a screen shot from a LabVIEW program that performs this benchmark. This example, in
LabVIEW 6i, is available in the download center of the Keithley web site as an example program
for the Model 2700. It uses NI-VISA to send SCPI commands to the 2700 over GPIB.
