When taking remote control of the
5340A
it
is
necessary to change only those cells that
are different from the above. For example, if the
5340A is to be used under remote con

trol,
1

to
18
GHz range, automatic searching, sample rate HOLD
and WAIT in output phase until addressed;
it
is
only necessary to change the ASCII

to

These changes can be made in any order.

What
is
Outputted
2
-
48. When addressed to TALK the 5340A outputs
a
string of 16 ASCII characters provided there
is
an addressed LISTENER on the bus. The handshake routine, necessary for passing infor
-
mation on the data lines, cannot be started unless there
is
both an addressed LISTENER and
TALKER on the bus.
The LISTENER must be able to recognize LF (line feed)
as
the end of the
5340A’s output data. As soon
as
the LISTENER accepts LF (sets DAC high) the 5340A leaves the
output phase and continues through its operating cycle.

Modes
of
Operation
‘
2
-
51. The 5340A has sevLrk1 remote operating modes. They depend on the Sample Rate and
Output modes and the
,mdhod used to initiate a measurement procedure. This section includes
a description of these modes,
a
simplified flow chart (Figure 2
-
5) showing all operating modes
and
a
sample program.
