Specifications describe the instrument’s warranted performance for the
temperature range of 23 ±3°C after a three hour warm-up. Supplemental
characteristics describe useful, non-warranted performance parameters.
These are denoted as “typical” or “nominal”.

Maximum input power operating level: 0 dBm
(1.0 mW)
Input power damage level: +20 dBm (100 mW)

.

31 Limited by maximum output power and system noise floor. Specified

for an IF bandwidth of 10 Hz, using a full 2-port measurement
calibration (including an isolation calibration performed with an
averaging factor of 16). Dynamic range is tested for transmission
measurements only; dynamic range for reflection measurements is
limited in practice by directivity.

32 The 85052D RF Calibration Kit was used for this measurement

calibration.
