ComB: Custom
Same like ComA. Please note that you have to use a null modem cable.
GPIB
If you want to use this interface you need a GPIB controller in your PC. You have just to set-
up the address of the LMG (in the range from 1 to 30).
4.4.2.1.2 remote <-> local
If you send any characters to the LMG it changes to the remote state (you see a ‘REM’ in the
status line). Then it is impossible to change any parameters like cycle time, because this might
conflict with an actual remote command.
To leave this remote state you can send an ‘go-to-local’ command via interface or you can
press the Goto Local softkey.
If you send further characters to the instrument it changes back to the remote state.
4.4.2.2 Processing signal interface (option L45-O3)
With IO you reach the set-up menus for the processing signal interface. With the rotary knob
you can select four tabs (‘A_In’, ‘A_Out’, ‘D_In’ and ‘D_Out’). By pressing the rotary knob
you can set-up each tab. Back returns to the IF/IO menu.
In the LMG450 you can install one ore two processing signal interface cards. So the number of
channels which are displayed in each menu depends on the number of installed cards.
4.4.2.2.1 Analogue
Input
tab
If you are in the setting mode of this menu, you can with the rotary knob select a channel.
Zero
Here you set-up, which value will be displayed with 0V input.
FS
Here you set-up, which value will be displayed with 10V input.
Example: You select Zero ‘30’ and FS ‘120’. Now you get with 0V input a display of 30, with
10V input a display of 120 and with 5V input a display of 75. The output is updated every
measuring cycle.
