2.13 Operating the R&S UPZ from the R&S UPP
The following screenshot shows the panel displayed when an input switcher and an
output switcher are connected (otherwise, only the lines relating to the recognized
switcher type would appear).
Fig. 2-27 Channel setting via the R&S UPP
Two lines are available for each switcher type, i.e. one for busbar A, the other for
busbar B. If any line is selected (by setting the black bar to the desired line), numerical
entry of the channel can be performed by pressing the SELECT key and confirming the
selection with ENTER. If ENTER is pressed instead of the SELECT key, the channel
can be selected by simply actuating the rollkey on the front panel. The channel number
set by means of the rollkey is immediately active so that the channels can be through-
connected by just turning the rollkey. Pressing a cursor key or ENTER terminates this
entry mode.
It is
not
possible to set the same channel to busbar A
and
B. The R&S UPP skips the
set channel.
Example:
Busbar B of the input switcher (address 0) is connected to input
4
and busbar A to
2
. If
4
is entered for busbar A, the direction is from bottom to top (towards higher numbers).
The R&S UPP thus changes the entry to
5
. If busbar A is to be connected to input
4
, B
should be previously set to another channel.
If busbar A had previously been on No.
6
, the R&S UPP would have changed the entry
to
3
. This means that the activated channel of the other busbar is always skipped by
1
.
If a suitable setup is available, channel numbers from 0 to 128 are permissible. Either
all 15 switcher addresses are occupied or the suitable R&S UPZ address has to be set
at the coding switch for entering higher channel numbers.
Channel number 0 means that all channels of all the switchers connected are opened.
The output switcher has a special feature as regards busbar B: It is possible to enter
–
1
as channel number. In this case,
all
channels of
all
switchers connected are closed
in busbar B, except the channel selected in busbar A. This setting is useful for worst-
case crosstalk measurements. If no channel is selected in busbar A (number 0), all
channels are closed in busbar B. This setting can be used to supply all DUTs
connected with signals for burn-in tests.
