Who has experience with the Anritsu MS4630A Network/Impeadance Analyzer?
I'm looking into replacing the 3577 with one. I like the HP to get basic impedance measurements but I have been looking around for a more modern option with more integrated analysis functionality. Unfortunatly, HP options are far outside my budget.
I was wondering how good and fast the Anritsu model is UI wise from someone which has used it.
If I compare the specs to the HP3577A, then HP has better specs accuracy wise (amplitude and phase) from an input level of about -80dBm downwards. Before that they are pretty similar. The specified accuracy on the HP really is a lot better <-80dbm and the "typical" spec curve blows the Anritsu away. However, Anritsu only specifies at rbw:1khz were it is comparable with the HP at rbw:1khz. But since HP specifies at lower rbw as well, it is much better on paper. Question is what is typical for the anritsu at lower rbw's?
Also, HP specifies accuracy at one frequency, which might be cherry picking as well.
Apart from that, the 3577 it is really old, has no analysis functionality to speak of, slow and has only 401 points vs 1001 for the Anritsu.
It also has a LCD. And it displays 4 Traces from 2 Inputs vs 2 Traces from 1 input for the 3577A.
The anritsu really has a ton of integrated analysis functionality which seems great to have. No Service manual thought.
The Anritsu I'm looking at has opt. 10 and 12 so input attenuator (-70-23dB output) and three receiver inputs (TR, TA, TB) like the HP (R,B,W).
One thing that worries me on the Anritsu is that it is sold with a dead psu (700 USD). And it has a HDD inside which might be dead as well. Does the Anritsu store cal data on the HDD or in separate eeprom? And is a HDD image available somewhere in case the hdd is trash?
