PNA - The standard for accuracy
All the network analyzers in the PNA family are known for their
high-levels of stability, contributing to accurate calibrations
and measurements. With the PNA-X, users can beneit from
exceptional levels of dynamic accuracy. For users in non-linear
environments, the PNA’s Scalar Mixer Calibration provides a
higher level of measurement accuracy.
Stability of a 20 GHz PNA over a 30-hour period¹
It is clear that the more stable the hardware, the better the
calibration, since it can correct the errors better. The calibration
will remain stable as a function of time and temperature, and
calibrations will not need to be updated as often.
Typical dynamic accuracy of a PNA-X, with –20
dBm power
If you are measuring a device with 20 dB insertion loss, the
contribution of the dynamic accuracy error (receiver linearity) is
less than 0.01 dB.
Scalar-mixer calibration versus a simple power
meter/receiver calibration
Note the effects of mismatch that are corrected for by SMC.
110 GHz PNA drift over a 24-hour period¹
As you can see on the graph, the 110 GHz PNA drifts less than 0.7
dB, after 24 hours, at 110 GHz. Keysight’s 110 GHz PNA system is
the most stable mmwave system in the industry.
