Specifications and Characteristics
The specifications and characteristics in this section describe the system
performance of the analyzer. Specifications are valid after the analyzer
has been turned on and allowed to warm up for at least one hour. The
system is as the network analyzer itself (which includes a built-m
transmission/reflection test set) and the following:
A calibration kit either HP 850323 (50 0) or HP 850363 (75 0)
A test port cable either HP part number 8120-6469 (50 or
HP part number 8120-6468 (75 0)
Specifications describe the instrument’s warranted performance over
the temperature range of
5 unless otherwise stated. These
specifications are valid only after the instrument has been turned on and
allowed to warm-up for at least one hour.
Supplemental
(indicated by italics) are typical, but
nonwarranted parameters, intended to provide information useful in applying
the instrument.
Receiver dynamic range is calculated as the difference between the maximum
receiver input level and the receiver’s noise floor. System dynamic range
applies to transmission narrowband measurements only, since reflection
measurements are limited by directivity.
Noise floor is as the mean of the noise trace at CW
frequencies. A signal at this level would have a signal/noise power ratio of
3 Noise floor is measured with the test ports terminated in loads, response
and isolation calibration, 15 Hz IF’ bandwidth, 0 test port power and
no averaging. Dynamic range specifications are listed later in the “Receiver
section of this chapter.
