Series 3700 System Switch/Multimeter User's Manual
Section 3: Rear Panel
3700S-900-01 Rev. C / July 2008
3-11
As described in the International Electrotechnical
Commission (IEC) Standard IEC 664, the Series 3700 is
Installation Category I and must not be connected to mains.
Pseudocards
You can perform open/close/scan operations and configure your system without
having an actual switching module installed in your Series 3700. Using remote
programming, you can assign a pseudocard to an empty switching module slot,
allowing the Model 3700S to operate as if a switching module were installed.
A pseudocard, which is essentially a "virtual switching module," cannot be
installed from the front panel. However, once the remote installation is complete,
you can take the Series 3700 out of remote mode and use the front panel.
Pressing the
LOCAL
or
EXIT
key takes the Series 3700 out of remote mode.
When the instrument is turned off, the pseudocard will be lost (uninstalled). In
order to recall a pseudocard, make it part of a saved setup.
NOTE
A saved setup retains the model number of the module installed in
each slot. The model number of a pseudocard is the same as the
model number of an actual module. This allows a saved setup to be
recalled provided the installed card (or pseudocard) matches the
model number for the slot in the saved setup.
Pseudocards programming example
Use the following command line to set the pseudocard of Slot 6 for 3720 Dual 1
x 30 Multiplexer card simulation:
slot[6].pseudocard = slot.PSEUDO_3720
Channel assignments
Each switching module has a certain number of channels. For example, the
Model 3720 switching module has 60 channels (1 through 60). When you
encounter a 1- to 3-digit channel number in this manual, the switching module
channel is the point of discussion. A 4-digit channel number includes the slot
number followed by the 3-digit channel number.
