855xxA/B Series CalPods and 85523B CalPod Controller Usage Information
Step 8. Configure the Hardware for a Calibration
Figure 1-2, “Basic Measurement Hardware Configuration for Calibration (2-Port DUT),” on page 1-19
shows a recommended, basic measurement hardware configuration for calibrating the PNA when
measuring a 2-port DUT. For information on more complex configurations, see the 855xxA/B Series
CalPod Information website at: http://na.support.keysight.com/calpod .
The following items may be required, depending on your measurement hardware configuration.
•
RF Cables – required to connect each CalPod to a PNA port. CalPods work well with cable losses
(one- way loss from CalPod to PNA test port) up to 20 dB. CalPods will also work with cable
losses greater than 20 dB, but the recorrection performance may be degraded. Consult the
855xxA/B Series CalPod Performance Characteristics document (85523-90007) available at:
http://na.support.keysight.com/calpod/calpod_pc_85523-90007.pdf
•
RF Adapters for the Device Under Test (DUT) – required if the DUT connectors are not compatible
with the CalPod RF2 (2.92 mm male) connector.
•
Calibration Kit or ECal – compatible with DUT connectors.
•
(Optional) CalPod Drive Cable Extensions – The standard CalPod drive cable is 2 meters in length.
The 85554A CalPod drive cable extension provides an additional 10 meter length. These CalPod
drive cable extensions can be cascaded.
