Keysight (Agilent HP) E8363A Repair Service

E8363A Microwave VNA 45MHz- 40GHz
We repair and calibrate the Agilent E8363A Vector Network Analyzer in our full-service lab. Obsolete equipment is our specialty. Free evaluations.
The Keysight E8363A vector network analyzer is a member of the PNA Series network analyzer platform and provides the combination of speed and precision for the demanding needs of today's high frequency, high-performance component test requirements. The PNA Series meets these testing challenges by providing the right combination of fast sweep speeds, wide dynamic range, low trace noise and flexible connectivity. The E8363A provides TRL/LRM calibration (four-receiver enabled) for waveguide, on-wafer, and in-fixture devices. Source attenuators, bias-tees and direct receiver access are optionally available for active device and extended dynamic range measurements.

Any failures or unforeseen issues identified during the calibration phase will be detailed in an estimate submitted for your approval prior to any further action. Repair charges are determined by the actual time and materials required. Please be aware that customers are responsible for all associated shipping costs, to and from our location. This initial estimate is provided free of charge.

Agilent E8363A Error Messages

The E8363A messages below are the ones that point to hardware, followed by what a failed performance test means on this model.

E8363A on-screen error messages

MessageMeaning and where to look
PHASE LOCK LOSTThe A11 phase lock board sees too little reference-receiver signal to lock. Cause can be in the source, signal separation (couplers, switch) or receiver path. Check the A10 frequency reference output and the reference receiver first.
SOURCE UNLEVELEDOn the E8363A check cables W37/W38 from the A23/A24 detectors to the A16 test set motherboard and W39 to the A21 SOMA 50. One port only: replace that port's detector. Both ports: replace A16.

E8363A failed performance test – likely cause

Failed testWhat it points to
Source power accuracy / linearityRun the source calibration adjustment; if it still fails, the source (A12 source) is suspect.
Source maximum power outputFollow the signal through the separation path (switch, couplers, attenuators) to find the loss.
Frequency accuracyMeasure the rear-panel 10 MHz REF OUT; more than about 10 Hz off calls for the 10 MHz reference adjustment.
Trace noiseRarely fails alone; run the receiver calibration adjustment, then suspect the A6 SPAM board.
Receiver compression / noise floor / dynamic accuracyPoints to the A31–A34 receivers or the A6 SPAM board. Receivers are identical, so swapping two channels confirms a bad one.
Calibration coefficientsTracking terms only: run the receiver calibration adjustment. Any other error term failing means a hardware fault.
System crosstalkLoose RF cable, or isolation loss in the receivers or the receiver/test set motherboard. Tighten all cables and receiver screws first.
