RTSA (Real-Time Spectrum Analyzer) Mode—Option 350 (CPU2 Only)
RTSA Mode Settings
—
Auto
When Auto is selected, the preamp setting is coupled to the RF
attenuation and to the acquisition. When the acquisition reaches a certain
value, the preamp is turned on and
PA
is shown to the left of the graticules
on the display.
Check for Compressed Measurements
Compression occurs when too much power into an amplifier causes it to no
longer amplify in a linear manner. When too much power goes into the
FieldFox RF Input connector, the amplifiers in the RTSA receiver compress and
signal power will not be displayed accurately. This can occur even if
ADC Over
Range
is not displayed because devices other than the ADC, such as the mixer,
might be compressed. Increase the RF Attenuation value to prevent the RTSA
receiver from being compressed.
How to Check for a Compressed Measurement
— Using a marker at the signal peak, make note of the signal power level.
— Increase the RF Attenuation level by 5 dB.
—If the signal level does NOT change, then NO compression exists. This
indicates that the signal is in the linear region of the FieldFox
receiver.
—If the signal level DOES increase, then the receiver was compressed.
Set the RF Attenuation value at the setting when further increases no
longer result in an increase in the displayed power level.
Spectrum Selection
To select the spectrum-type for your measurement:
How to make Spectrum Settings
— Press
Measure 1
— Then Press:
—
Density Spectrum
The signal displayed is a real-time spectrum with
a histogram bitmap. Refer to
—
Spectrogram
The signal is displayed is a real-time spectrum with a
spectrogram bitmap. Spectrogram views are valuable in capturing
signals that include both time and frequency variations. Refer to
.
Density Spectrum and Spectrogram data is lost when you change modes,
because the FieldFox optimizes the instrument’s resources during mode
changes.
