Corrected System Performance
The specifications in this section apply for measurements made with the N5241A, N5242A, and N5249A analyzer with
the following conditions:
 10 Hz IF bandwidth
 No averaging applied to data
 Isolation calibration with an averaging factor of 8
 Source in filtered mode where applicable
System Dynamic Range and Receiver Dynamic Range
 System Dynamic Range is defined as the max leveled output power (spec) minus the noise floor (spec).
 Extended Dynamic Range at Direct Access Input is defined as the specified source maximum output power
(typical) minus the direct receiver access input noise floor (typical).
 Receiver Dynamic Range is defined as the test port compression at 0.1 dB (typical) minus the noise floor (typical).
Note
The effective dynamic range must take measurement uncertainties and interfering signals into account.
The direct receiver access input extended dynamic range is calculated as the difference between the direct receiver
access input noise floor and the source maximum output power. This set-up should only be used when the receiver
input will never exceed its maximum receiver input. When the analyzer is in segment sweep mode, it can have
predefined frequency segments which will output a higher power level when the extended dynamic range is required
(i.e. devices with high insertion loss), and reduced power when the maximum receiver input level will occur (i.e. devices
with low insertion loss). The extended range is only available in one-path transmission measurements.
It may typically be degraded at particular frequencies below 500 MHz due to spurious receiver residuals.
