in its remote programming storage cells the initial conditions of 0, P,
There are:

-
J Internal Sample Rate

N Local operation
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 Hz resolution, 10 Hz
and WAIT in output phase until addressed; it is only necessary to change the ASCII "J" to

2-47. What is Outputted

2-48. When addressed to TALK the 5340A outputs a string of 16 ASCII characters provided there
a n addressed LISTENER on the bus. The handshake routine, necessary for passing infor-
is
mation on the data lines, cannot be started unless there is both a n addressed LISTENER and
TALKER on the bus. The LISTENER must be able to recognize LF (line feed) as the end of the
output phase and continues through its operating cycle.
2-49. The 16 output characters, their description and the order in which they are outputted are
shown in Table 2-5. Refer to Table 2-2 for signal levels.

2-50. 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 sample program.
