Product model
E8364B Microwave Network Analyzer 10MHz-50GhzServices
Our technicians repair and calibrate the Agilent E8364B Network Analyzer in-house. Analyzers are our business. Free evaluations, veteran owned.
Description
The microwave PNA Series instruments are integrated vectorrnnetwork analyzers equipped with a built-in S-parameter test set,rnsynthesized source, hard and floppy disk drives, and LCD display.
The E8362B analyzer has two 50 ohm, 3.5 mm (m) test ports.
The E8363B and E8364B analyzers have two 50 ohm, 2.4 mm (m)rntest ports.
Repair prices
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 E8364B Error Messages
This E8364B list covers the on-screen errors that matter for repair and the board each one leads to.
E8364B on-screen error messages
| Message | Meaning and where to look |
|---|---|
| PHASE LOCK LOST | The 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 UNLEVELED | On the E8364B 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. |
E8364B failed performance test – likely cause
| Failed test | What it points to |
|---|---|
| Source power accuracy / linearity | Run the source calibration adjustment; if it still fails, the source (A12 source) is suspect. |
| Source maximum power output | Follow the signal through the separation path (switch, couplers, attenuators) to find the loss. |
| Frequency accuracy | Measure the rear-panel 10 MHz REF OUT; more than about 10 Hz off calls for the 10 MHz reference adjustment. |
| Trace noise | Rarely fails alone; run the receiver calibration adjustment, then suspect the A6 SPAM board. |
| Receiver compression / noise floor / dynamic accuracy | Points to the A31–A34 receivers or the A6 SPAM board. Receivers are identical, so swapping two channels confirms a bad one. |
| Calibration coefficients | Tracking terms only: run the receiver calibration adjustment. Any other error term failing means a hardware fault. |
| System crosstalk | Loose RF cable, or isolation loss in the receivers or the receiver/test set motherboard. Tighten all cables and receiver screws first. |
SCPI error ranges
| Range | Class |
|---|---|
| −100 to −199 | Command errors |
| −200 to −299 | Execution errors |
| −300 to −399 | Device-specific errors |
| −400 to −499 | Query errors |
