the 2020 dependent on the indicated frequency on the 2010. It is possible
to connect two different pins on the 2010 to the same pin on the 2020.
This may be useful to synchronize the selectivity of the 2020 and the 2010,
when a 8 & T programme is used on the analyzer. For example, if the
sockets are interconnected as shown in Fig.6.10 and the 8 & T PROGRAM
selector on the 2010 is in position "3", and theSE LECTIV lTV CONTROL
is on "100Hz", then the filter bandwidths on the 2010 and 2020 have the
same value and are switched synchronously throughout the frequency range.
However, if both the 2010 and the 2020 are to be remote controlled by
some external apparatus, the scanning facility on the 2010 must be electri-
cally driven (see section 4.6.2). Parallel connections must be made between
the pins of the REMOTE BANDWIDTH CONTROL socket on the 2020,
and the EXT. 8 & T PROGRAM socket on the 2010. Interconnection to
perform the same operation given in the preceding example is shown in
Fig.6.11. The switching is remote controlled by grounding the termination
corresponding to the filter bandwidth required.
