Hi,
Some enquires on the E3238S Signal Survey System
1) Can i use LAN instead of firewire connection from E3238S to PC?
2) What is the scan rate for VHF and UHF?
3) For FHSS modulation, what is the maximum and minimum hop rate?
4) For the record option, what is the format of the audio signal stored at?
5) Where can i download a trial version of the software? SSY* - RF Sensor Measurement Synchronization and N6829A audio player
6) For antenna, any preferred vendors i can work with or recommendation?
7) Are there any application notes on using 3 units of E3238S system to do triangulation to locate a specific point?
Can any experts in this field PM me?
Thanks.

Yes, with the VTI Technologies EX2500A Gigabit LAN I/O module. It can replace the E8491B Firewire connection and can provide faster I/O to the VXI mainframe.(http://www.vtitech.com)
2) What is the scan rate for VHF and UHF?
The sweep rate for the E3238S system is greater than 10 GHz / second with a 7.5 KHz RBW for both VHF and UHF.
3) For FHSS modulation, what is the maximum and minimum hop rate?
Sample rate of the ADC is 95 MS/second; each sample is 16 bits, which provides a 40 MHz bandwidth. So if all the hops were in the same 40 MHz bandwidth then the detectable hop rate would be around 10 nanoseconds.
4) For the record option, what is the format of the audio signal stored at?
There are multiple recording options for the E3238S system. I have listed them below:
1) - NBR Narrow band recorders, each 32 channel DDC offers 32 channels of narrow band recorders. Maximum BW for each channel is 400 KHz.
2) - Time Snapshots, raw IQ time samples, saved to the memory in the ADC. This provides 8 seconds of recording at full 40 MHZ BW
3) - Wideband Record Playback, adding a external disk array can provide 24 Hours of recording of raw IQ time samples at 40 MHZ BW
4) - Frequency Snapshots provide spectral data points from the Frequency Domain (Spectrum) at the time the recording starts.
Each of the above recordings has a different format and the data formats are documented in the E3238S product technical manuals.
5) Where can i download a trial version of the software? SSY* - RF Sensor Measurement Synchronization and N6829A audio player
The software by itself will not be of much use without the hardware and the software is over 1 GByte in size making downloading the SW impractical. However, if you send me an email with your address I can have a local Agilent field sales engineer work with you to provide a complete demo, both hardware and software.
6) For antenna, any preferred vendors i can work with or recommendation?
The Antenna needs to be selected for your specific application. There are hundreds of antenna choices covering different frequency ranges and applications. There are highly selective antennas and broadband antennas, Omni-directional and directional antennas. So, in order to answer this question properly I would need to know more about your application and frequencies of interest.
7) Are there any application notes on using 3 units of E3238S system to do triangulation to locate a specific point?
Yes, we have a couple of different techniques to address geo-location of unknown RF emitters.
1) Time Difference of Arrival (TDOA) with our N6854A product. Literature on this can be found on Agilent.com search for N6854A
2) Wideband DF with integrated SQL database and triangulation with the integrated solution from TCI (SLIC-903 system) (http://www.tcibr.com)
I do not actively monitor this forum so please email me any addition questions directly.
