Method 3: Single-Sided-Spur - Agilent Technologies E5500A User Manual

Method 3: Single-Sided-Spur

Document Part No. E5500-90024Ed. 1.0
Advantages
G
Will measure source without modulation capability.
G Calibration is done under actual measurement conditions so all
non-linearities and harmonics of the AM detector are calibrated
out. The double-sided spur method and the single-sided-spur
method are the two most accurate methods for this reason.
Disadvantages
G Requires 2 RF sources, which must be between 10 Hz and 40 MHz
apart in frequency.
G
Requires an RF spectrum analyzer for manual measurement of
the signal-to-spur ratio and spur offset.
Procedure
1
Connect circuit as shown in
connections. If the Agilent 70420A Option 001 or Agilent 70427A
is available, use one of the connection diagrams described in
Noise Measurement Block Diagrams"

2 Measure the power which will be applied to the AM detector. It
must be between 0 and +23 dBm.
