Remote Operations
Model 2701 User’s Manual
Operation enhancements
There are some operations you can do over the Ethernet and RS-232 interface that you
cannot do from the front panel. The more important ones are summarized below.
Pseudocards
Using remote operation, you can assign a pseudocard to an empty switching module slot.
With a pseudocard installed, the Model 2701 will operate as if the switching module is
installed in the Model 2701. This feature allows you to configure your system without
having the actual switching module installed in the unit. There is a pseudocard for every
Keithley Model 7700 series switching module.
A single SCPI command (SYSTem:PCARdX, where X=1 or 2) is used to install a
pseudocard in an empty switching module slot. Details are provided in Section 2.
A pseudocard cannot be installed from the front panel. However, once it is installed, you
can take the Model 2701 out of remote and use the front panel. When the instrument is
turned off, the pseudocard will be lost (uninstalled).
Autozero
Autozero is part of the normal measurement process to assure stable, accurate
measurements. Autozero can be disabled to increase measurement speed. However, the
readings will eventually become inaccurate over time and temperature changes.
Autozero can only be disabled using remote programming. It cannot be disabled from the
front panel. Autozero is covered in Section 3.
dB calculation
Using remote programming, you can select the dB calculation for DC or AC voltage. The
dB calculation makes it possible to compress a large range of measurements into a much
smaller scope. See Section 5 to select and configure the dB calculation.
You cannot select dB from the front panel. However, once it is selected you can take the
Model 2701 out of remote and use the front panel. When the instrument is reset to default
conditions (or turned off), dB will be lost.
