Interconnect Cables
There are two different cables available for connecting the HP E1586 Rack
Mount Terminal Panel to the HP E1313/E1413 Option A3F. In both cases,
four cables are required if all 64-channels are needed. This also requires
two HP E1586A Rack Mount Terminal Panels since a single Terminal Panel
only connects 32 channels. The cables do not come with the
HP E1313/E1413 Option A3F and must be ordered separately. The cables
are described in the following paragraphs.
Standard Cable This cable (HP E1588A) is a 16-channel twisted-pair cable with an outer
shield. This cable is suitable for relatively short cable runs.
Custom Length Cable This cable (HP Z2220A Option 050) is available in custom lengths. It is a
16-channel twisted-pair cable with each twisted-pair individually shielded to
provide better quality shielding for longer cable runs.
Mounting the
The Terminal Panel can be mounted in a standard size instrument rack. To
HP E1586A Rack minimize temperature gradients across the panel, it should be mounted in
the rack such that it is away from the other heat sources. The bottom of the
Mount Terminal Panel
rack is usually the preferred location. Take particular care to minimize the
temperature differences across the horizontal width of the Terminal Panel,
since it is most susceptible to horizontal temperature gradients across its
longest dimension.
HP E1586A Option 001
Optional high frequency common mode filters on the HP E1586A Rack
HF Common Mode Mount Terminal Panel's input channels filter out AC common mode signals
present in the cable that connects the terminal panel and the device under
Filters
test. These filters are useful for filtering out small common mode signals
below 5Vp-p. To order these filters, order HP E1586A Option 001.
