Operating a Master/Slave Setup
Two
HP
83750 series sweepers can be configured for two-tone measurement
capabilities. Two synchronously tracking sweepers can be configured as a
“master/slave” pair for mixer characterization or inter-modulation distortion
measurements. The swept frequency accuracy allows control of the sweepers
at Exed- or swept-frequency offsets.
To implement master/slave operation, configure the sweepers as shown in
Figure 6-l. The master sweeper generates the 10 MHz frequency reference
for both sources. The source synchronization cable (HP part no. 83750-60059)
must be connected between the auxiliary interface connectors on the rear
panels of the sweepers.
When conEguring a two-tone measurement system, the slave does not need
to interface with any instruments other than the master. The master should
interface with the display device (scalar analyzer or oscilloscope, for example)
as if it were a stand-alone sweeper.
