Specifications

The N9340B INM shows spectrogram and

spectrum trace on the same screen.

Extended spectrogrammonitoring (Option INM)

Option INM extends the N9340B spectrogram capability further with the ability

to continuously monitor and save spectrogram data over time not only to the

analyzer’s internal memory or a USB flash drive, but also directly to a PC. With

option INM users can save more than 1,500 continuous frames of data depend-

ing on the size of the USB flash drive or PC memory.

Option INM also supports an Automatic Save function. The N9340B can save

the spectrogram at a user specific time or at a set interval of frame. All the

small files with the same prefix can be combined into one file using N9340 PC

Software, making analysis easier.

The user can choose among the 3 display modes: spectrogram only, spectrum

trace only or the combination of a spectrogram and a spectrum trace in one

screen. Limit lines with pass/fail functionality is also available in this measure-

ment. The N9340B will identify the failed frame of spectrogram data with a

red mark. The Pass/Fail test can also provide alerts. Users may use marker to

find the previous/next frame failed data to quickly find the offending event or

interference. The spectrogram data may be played back for review on either the

analyzer’s display or on a PC utilizing N9340B PC Software.

With the option INM, the Agilent N9340B spectrum analyzer can provide

unattended monitoring of communication systems capturing performance

or intermittent events like interference over extended periods of time – days

rather than hours. The option INMcan provide additional value for the wireless

network communication system managers, hospital administrators, etc. as well

as police and homeland security by recording spectrogram measurement results

over time.
