Handheld Spectrum Analyzer (HSA)

N9340B

07

N9340B supports Meter and Chart mode to display the

results of power measurements.

N9340B supports U2000 series USB power sensors

for high accuracy power measurement.

The field strength measurement automatically takes into the

account of the antenna factor. The antenna table is definable

by the standard N9340B PC software.

High accuracy power

measurement

The N9340B now supports high-accuracy,

USB plug-and-play power measurements

as standard when connected to an Agilent

U2000 series USB power sensor. Make

true average power measurements for all

signal types with wide dynamic range up

to 18 GHz with just the push of a button.

The Agilent U2000 USB sensors require

no external power supplies and with internal

zeroing eliminate the need for external

calibration. Without the need for additional

boxes, the user can easily set up, calibrate

and control the power meter/sensor via

the analyzer’s USB port. The N9340B

can collect, display and save the power

meter results.

The analyzer also provides Pass/Fail testing

with user set upper and lower limits and a

Pass/Fail indicator. Test results are shown

in dBm and W when making absolute

measurements and in dB and percentage

when measurements are relative. Two display

modes are available: Meter or the Chart mode

to log power measurements over time.

Field strength measurement

Field strength measurement

Electric field strength measurements are

frequently required for field testing of

transmitter and antenna coverage. Field strength

measurements are now a standard function in

the N9340B. Calibrated field strength

measurements are easy to make once the

antenna factors are loaded into the analyzer via

the provided PC software based antenna

template. Either field strength (in dBµV/ m,

dBmV/ m, or V/m) or power flux density

(in dBm/m or W/m ) can be displayed. With

the amplitude offset function, the user can

correct gain or loss. And finally together

with the user-definable multi-limit line function,

the N9340B offers the user quick and convenient

field strength measurements and analysis.

The Waveform of FSK also shows the metrics

with detailed parameters.

Channel table

For the users who prefer to tune the spectrum

analyzer according to channel numbers rather

than center frequency, you will find the new

Channel Table feature easy-to-use. The

Channel Table includes the major wireless

communication standards, such as AMPS,

GSM/EDGE/GPRS, CDMA, CDMA2000 etc.

The Channel Table can also be edited by the

user with the included N9340 PC Software.

The revised Channel Table can be

downloaded to the analyzer via a PC USB

cable or a USB memory stick.

The channel table offers the ability to tune N9340B

according to channel numbers.

The channel table is editable by N9340B PC software.
