Performance Verification Tests
The design, specifications and support of the Agilent N5531S Measuring Receiver
System relies on the spectrum analyzer, power meter and sensor modules meeting
their normal specifications. A N5531S system calibration is not required. If each
instrument is tested separately and passes all specification verification testing,
when the instruments are combined as a system; system specifications are
guaranteed. Most system specifications are tied directly to the spectrum analyzer
specifications. Only the RF Power Level and Absolute TRFL measurements use
the power meter and the sensor modules.
Agilent service centers have calibration software for each instrument in the
system. Customers can purchase a copy of this software for the spectrum analyzer
and the power meter.
Specifications were developed by modeling the system, deriving performance
from the published instrument specifications for the individual instruments, and
applying an error budget for each instrument. Bench testing was performed to
verify the modeling and specification derivation is correct.
When performing measurements it is very important for the user to refer to the
NOTE
Measuring Receiver Specification footnotes. The footnotes explain instrument
settings and measurement guidelines required to provide specified measurement
results.
Although the measuring receiver specifications are guaranteed by design and no
measuring receiver testing is required, there may be a need to verify the Tuned RF
Level specification. The following procedure outlines how to verify the linearity
specification portion of TRFL and how to test TRFL over all three measurement
ranges.
