Hi,
In my laboratory I have two XA-Series spectrum analyzer.
- EXA 9010A 10Hz - 32GHz (13.12 firmware)
- MXA 9020A 20Hz - 8.4GHz (13.15 firmware)
I'm make a program that download I / Q signals from these analyzers and I have two problems:
*First problem*
EXA I/Q settings:

MXA I/Q settings:
!http://i59.tinypic.com/350unb6.png!
The MXA spectrum analyzer do not have "Sample Rate" settings, that I use. I was wondering why ?!?!?
*Second problem*
If I download a I/Q data vector (with command READ:WAV0?), the sequence of I/Q raw byte are perfect using TCP/IP connection on port 5025, but if I use Telnet mode on 5023 port I have some problem with data. What is that wrong ?
Thanks very much.

The Sample Rate feature in the I/Q Waveform measurement is only available when the analyzer is equipped with Option DP2, Digital Processing and 2 GB Capture Memory. This option is installed on any X-Series analyzer that has hardware capable of analysis BW of 40 MHz or wider.
The following wizard will help you determine what hardware upgrades are necessary for your MXA to get DP2 along with an upgrade to add Option B40. http://rf-test.tm.agilent.com/selector/
The issue of waveform data not being read correctly when queries using Telnet but reads are correct if a TCP/IP connection is used may be a result of the timeout settings. If you are using REAL,32 format, for example, the 2728 samples of data requires 21,824 bytes of data. The time required to transfer this amount of data might exceed the current timeout setting (typically between 3 seconds and 5 seconds).
If the problem is something other than a timeout issue, we would need more details describing the issue to help us determine a possible solution.
