Spec analyser 8560A Option 8560E?

[Andrew]

I've just bought a HP8560A spectrum analyser (sorry for UK spelling).
The front panel tells me it is a 8560A. When it first turns on it
writes 8560E to the screen, also in CONFIG / DATECODE & OPTIONS it
lists 8560E and 002 (002 is the tracking generator).

It seems to have the features of the 8560E, 1Hz RBW and fancy power
measurement options.

I've searched the web but cannot find out the scope of this upgrade.
Can anyone please enlighten me more? Has the spec of a 8560E or is it
some in-between animal.

The 856x series analyzers had plug-in ROM sets to allow for firmware
upgrades. I have an early 8562A (1987), and I found that HP had a new ROM
set that included things like FFT functions, etc. The I found that there
were 4 and 5 ROM chip sets. After I ordered and installed the right chip
set, I found that my machine complained of several internal faults on
power-up. I got tired of playing around, and put the original ROMs back in.

Who knows what somebody may have plugged into your 8560A; just be happy it
works!
