        Models 707B and 708B Switching Matrix Reference Manual 

4-6 

707B-901-01 Rev. A / August 2010 

 

Front panel 

The front panel of the Keithley Instruments Model 707B or 708B contains the following items: 

•

 The 

display 

•

 

The crosspoint display (Model 707B only) 

•

 

The keys and navigation wheel 

 

•

 

The LAN status indicator 

•

 

The POWER button 

You can use the keys, displays, and the navigation wheel 

 to change the selected channel or 

channel pattern. You can also use them to access, view, and edit the menu items. The crosspoint 
display on the Model 707B shows you which channels are opened and closed. 

The small display is a two-line vacuum fluorescent display (VFD). 

 

Upper crosspoint display (Model 707B only) 

The larger upper display on the Model 707B mainframe provides a visual means of determining the 
relay status of each card slot in the instrument at any given time. It also shows the label names for 
each row and column of the given slot.  

The crosspoint display may be operated from the navigation wheel 

 to scroll through the slots 

displaying the status. You can use the navigation wheel 

 to select channels for relay open or 

closures or other actions. 

For details on indicators and additional options, see 

Crosspoint display (Model 707B only)

 (on page 2-

15).
