Measurements Using the Tuned Receiver Mode
In the tuned receiver mode, the analyzer’s receiver operates independently of any signal
source This mode is not phase-locked and functions in all sweep types. The analyzer tunes
the receiver to a synthesized CW input signal at a precisely specified frequency. All phase
lock routines are bypassed, increasing sweep speed significantly. The external source must
be synthesized, and must drive the analyzer’s external frequency reference. The analyzer’s
internal source frequency is not accurate, and the internal source should not be used in the
tuned receiver mode.
Using the analyzer’s tuned receiver mode is useful for automated test applications where an
external synthesized source is available and applications where speed is important. Although
the tuned receiver mode can function in all sweep types, it is typically used in CW applications.
Typical test setup
Activate the tuned receiver mode by pressing .
2. Connect the equipment as shown in Figure 2-56 to perform a CW measurement using the
tuned receiver mode.
