What does PSA Option 233 Measuring Receiver
Personality Do?
PSA Option 233 is the firmware that controls the N5531S Measuring Receiver
System and provides the user interface for the Measuring Receiver personality
embedded in PSA. It enables you to make the following measurements:
• “Frequency Counter Measurement” on page 66 - Used to accurately tune to and
measure the carrier frequency.
• “RF Power Measurement” on page 70 - Measures the RMS RF power of the
signal by using the Power Meter with a sensor module.
• “Tuned RF Level Measurement” on page 74 - Measures the absolute or relative
levels of continuous wave RF signals to extremely low levels.
• “AM Depth Measurement” on page 82 - Measures the amount of amplitude
modulation of an RF carrier.
• “FM Deviation Measurement” on page 87 - Measures the frequency deviation
of the tuned input signal.
• “PM Deviation Measurement” on page 93 - Measures the phase deviation of
the tuned input signal.
• “Modulation Rate Measurement” on page 99 - Measures the modulation rate of
a modulated AM, FM, or PM signal.
• “Modulation Distortion Measurement” on page 103 - Measures the modulation
distortion applied to the modulated signal by comparing the ratio of harmonic
and noise power to total power.
• “Modulation SINAD Measurement” on page 107 - Measures the modulation
noise and distortion applied to the modulated signal by calculating the ratio of
total power to harmonic and noise power.
• “Audio Frequency Measurement” on page 111 - Measures the audio frequency
of an audio signal applied to the Audio Input port.
• “Audio AC Level Measurement” on page 113 - Measures the true RMS level of
an external signal.
• “Audio Distortion Measurement” on page 115 - Measures the amount of audio
distortion applied to the audio signal by comparing the ratio of harmonic and
noise power to fundamental power.
• “Audio SINAD Measurement” on page 117 - Measures the amount of audio
SINAD to the audio signal by comparing the ratio of fundamental power to
harmonic and noise power.
• “Auto Carrier Frequency Triggering and CCITT Filtering” - As of PSA
firmware revision A.11.08 these are available in Option 233 as standard
features. Previously, these features were only available with licensed Options
23A and 23B. For backwards compatibility, it may be necessary to license
these two options so they will appear on the Show System screen, or can be
queried using the *OPT? SCPI command. Please contact Agilent Technologies
if license keys are required.
