I have a R2670 and am trying to perform front end filter alignment on my APX. I set a test signal with no modulation at -14dbm at the lowest test frequency and the RSSI number barely spiked. The tuner complained check input rf signal. I tried the highest frequency and the tuner was able to perform auto tune but only when it is at 0dbm. I was connected to the GEN out port of the analyzer.

any idea why this is happening

Just an FYI to check on your monitor......
BOTH the generator out AND the RF ANTENNA ports ( BNC connectors ) are fused.
Simply unscrew the BNC and check the little green pico fuses.
They are like 1/16 amp or something very small.

Is this a legit radio or an ALT radio? I've seen ALT radios do real funky things when tuning the FEF.

You were right! Whadayaknow!

I actually had another 2670 and all is well now.

Now that is the kind of help we need around here! Good post

250 mA on my R2590.

If you value the life of your monitor, do not replace these with higher-amperage fuses. They are there to protect the generator and receive circuitry from overload should you accidentally key a radio into them, or hit them with a strong near-field RF source.
