Apr 6, 2015 · I tried this (via an anti alias LPF) in the E4406A and the E4406A limited out at -136dBc/Hz at maybe 3-10kHz offsets. Not bad! The idea would be to use an external LO and mixer to make a fairly decent phase noise measuring capability if a coax relay was fitted here. Note: My E4406A has the 14bit IF module which will help here.

Mar 23, 2019 · The E4406A VSA *is* a Spectrum Analyzer (VSA = Vector Spectrum Analyzer, i.e. it uses FFT for spectrum analysis), however since it was designed for testing cell phone transmitters it comes with various limitations, like a max span of 10Mhz (or 100Mhz with the HSDPA software option).

Oct 14, 2015 · My system is WIN XP 32bit SP2, E4406A Hardware is FW A.10.08 If I use SCPI commands via telnet it works fine. Both TELNET and Socket ports are ON. I've tried fresh windows installation with 89600 V9.02, V11.21, V12.02 I'm sure that I'm missing something, any help will be greatly appreciated.

Nov 11, 2016 · For posterity, he was referring to these: My E4406A would generally boot up about 5-10 minutes after turning on the power, but lately it was taking more like 30 minutes to 1 hour so it was time to deal with it. The 47 uF cap showed higher-than-normal ESR when cold, but was close to normal when warm. The 33 uF cap was almost completely open.

Sep 15, 2020 · This is a bit of a necropost, but this is *the* thread that comes up when searching Google on the topic of E4406A and the 89600 VSA software. I just got this working so I thought I would share what was involved. This will allow one to use unsupported VSA software with their unsupported Agilent E4406A.

Oct 20, 2015 · Hello My E4406A has a low frequency drop off at about 200Khz--some have wondered about if the front end 7dB attenuator also have a dc block inbuilt! I have replaced this attenuator with a pecision narda--and the answer is simple-yes the original made by weinschel have a dc bloc,so now my E4406A goes down to a few Hz.Now using an external dc ...

Dec 8, 2008 · The E4406A requires that you manually set an IP address. Using the 89601A software will allow you to demodulate many digital formats. Likewise, you can use the E4406A to capture I/Q data and use MATLAB to demodulate it. The E4406A has 1 mega sample capture memory and 8 MHz bandwidth.

Aug 12, 2020 · The instrument in question, E4406A, turns on abnormally. The first startup was successful but disconnecting one or more cards, RF IF SINCH. I replaced the two 100k resistors on the fan board, thanks to a suggestion from the forum.

Sep 22, 2019 · Thank you guys for sharing the information about the E4406A. I recently acquired one from Ebay. It is a very nice VSA but the flash memory on my E4406A is limited. I bought a used E4406-60060 CPU board that came with a flash memory card installed with it. I want to upgrade the flash memory card for it but it did not come with a utilities disk.
