Specifications

The Option A3F
Option A3F allows a VT1419A to be connected to a VT1586A Rack Mount
Terminal Panel. The option provides four SCSI plugs on a Terminal Module to
make connections to the Rack Mount Terminal Panel using four separately ordered
SCSI cables. Option A3F is shown in Figure 2-20.
Rack Mount Terminal
Panel Accessories
There are two different cables available to connect the VT1586A Rack Mount
Terminal Panel to the VT1419A Option A3F. In both cases, four cables are required
if all 64-channels are needed. These cables do not come with the VT1419A
Option A3F and must be ordered separately.
Standard Cable
This cable (VT1588A) is a 16-channel twisted pair cable with an outer shield. This
cable is suitable for relatively short cable runs.
HF Common Mode Filters
Optional High Frequency Common Mode Filters are on the VT1586A Rack Mount
Terminal Panel’s input channels (VT1586A-001, RF Filters). They filter out ac
common mode signals present in the cable that connects between the terminal panel
and the device under test. The filters are useful for filtering out small common
mode signals below 5 V
P-P
. To order these filters order VT1586A-001.
