Antenna Analyzer Quick Initial Check-Up Procedure Instruction

In many cases, when customer attempts to return “defective” (according to him) instrument to the store, a quick and easy initial check up may be performed in order to determine if the instrument is indeed defective, and, in case it is, to find out if it’s a warranty case or just the end user’s fault.

Ideally, everyone should have a small, hand tightened 50 Ohm dummy load, both with N-connector and with PL259 (like CELLWAVE).

1. First, you should visually examine the N-connector on the instrument (Except AA-35 Zoom, AA-55 Zoom, Stick 230 and Stick 500 – which have SO-239) for damage. In many cases the customers damage N-connector (even accidentally, without knowing it) by attempting to connect PL259 connector to it.

2. If the connector is not damaged, next step would be connecting known good dummy load to it and measure SWR. Depending on the quality of the Dummy Load and the frequency on which the measurement is being performed, the SWR shouldn’t be more than 1.1-1.2 and the instrument should show the “∞” symbol after disconnecting the load.

3. Perform self tests (for all Antenna Analyzers except “Stick” models). They are in the menu, usually under the “Tools” sub-menu. Please be aware that self test #3 requires a dummy load to be attached DIRECTLY to the Antenna Analyzer’s connector without any jumpers or adapters. Self tests should be performed on fully charged batteries or on power from the USB port.

We hope that this simple procedure would help you to eliminate many unnecessary returns.
