Analog
Sweep Mode
The following procedure details the steps necessary
to perform master-slave operations in the analog
sweep frequency mode.
Initial Setup
1. Set up the Master and Slave 681XXAs as follows:
a. Begin by resetting both sweep generators.
b. On both instruments, press
Analog
to place
them in analog sweep mode, then select the
sweep range, power level, and any frequency
markers for each.
c. On the Master sweep generator, set the sweep
time and select a sweep trigger mode.
d. When finished, press
CW
on both sweep gen-
erators to place them in CW mode, then press
SYSTEM
on each. Both units now display the
System Menu (shown below).
e. On the Master 681XXA, press
Master
; on the
Slave 681XXA, press
Slave
.
f. Return both sweep generators to CW mode by
pressing the main menu key
CW/SWEEP
SELECT
g. Now press
Analog
to place both sweep gener-
ators in analog sweep mode. This starts mas-
ter-slave operation.
Resynchronizing after Parameter Changes
In analog sweep frequency mode, any parameter
change on either sweep generator during master-
slave operation causes the swept frequency output
signals to become unsynchronized.
To resynchronize the swept frequency output sig-
nals after making a parameter change, first put
both instruments in CW mode, then place them
back in analog sweep mode.
