HP E1586A Rack Mount Terminal Panel

Description

Connecting to VXIbus Instruments

Interconnect Cables

Standard Cable
The HP E1586 Rack Mount Terminal Panel provides extended connections
to certain VXIbus instruments, like the HP E1413C High Speed A/D
Converter, HP E1415A Algorithmic Closed Loop Controller, and HP
E1476A 64-Channel T/C and Low Offset Relay Multiplexer. The Terminal
Panel is recommended if the VXIbus instruments are located a distance
away from the measurement connections. The Terminal Panel provides up
to 32 3-wire connections to allow for 32 channel connections to the VXIbus
instruments.
Since the Terminal panel only provides 32 channels, use an additional HP
E1586 Terminal Panel when using it with an HP E1413C, E1415A, or
E1476A.
The Terminal Panel also provides three on-board thermistors for sensing the
isothermal reference temperature of the Terminal Panel. The three
thermistors provide substantial accuracy improvements when temperature
gradients are generated across the length of the Terminal Panel.
The HP E1586 Terminal Panel can be ordered with optional High Frequency
Common Mode Filters (i.e., HP E1586 Option 001, RF Filters). These filters
are connected to the input terminal and are used to filter out AC common
mode signals present in the cables that connect between the terminal panel
and the device under test. The filters are useful for filtering out small
common mode signals below 5 Vp-p. To order these filters, order HP E1586
Option 001.
Figure 1 on page 6 shows how to connect the Terminal Panel to a VXIbus
instrument. The connections are made to an HP E1413C Option A3F
Terminal Module.
The panel uses SCSI cables to make the connections to the VXIbus modules.
Note that the modules must have the correct Terminal Modules (e.g., HP
E1413C/E1415A Opt A3F) installed to make these connections. Each cable
provides connections for 16-channels thus each Terminal Panel requires two
cables to make 32-channel connections.
The cables do not come with the Terminal Panel and must be ordered
separately. The available cables described in the following.
This cable (HP E1588A) is a 16-channel twisted pair cable with an outer
shield. This cable is suitable for relatively short cable runs.
