Robin,
Do you have the Service Guide (08590-90316) and Component Level Information Package (5963-2591, sometimes 5963-2951)?? Both are available on the Keysight website.? They should help you trace where the amplitude drops.

Hi,
?
I have an 8592L that has a level discrepancy between high and low bands ... of around 16dB, its the high band that is measuring flat, but low. ... it's not the mixer, that has been swapped for a known worker with exactly the same result (+- 0.5dB) ...? the amplitude, frequency and YTF cals complete without issue ... where to look next?
?
I bought this with a blown mixer, the upper range was down, the lower range was dead.?? Swapping the mixer for a known good one has restored the low range to full function, but the upper range still has the same low level ...
?
Ideas?
