4.2. Transmitter power measurement
By using an SMA to RP-SMA cable, connect your RF signal source to the SMA socket
of the tester. Please watch the difference between SMA and RP-SMA ends of the cable.
Please also make sure the RF power is
less then 1 Watt, since larger power may
permanently damage the tester.
Since some transmitters (such as Wi-Fi
access points) operate in pulse mode,
peak power (maximum measured power
over an interval of about 1 second) is
displayed on the screen.
As usual, the
(OK) key will hold the measurement, and the
(menu) button will
display a help screen for this operating mode.
4.3. Spectrum analyzer
There are three modes the RigExpert IT-24 can display spectrum of the input RF signal.
In each mode, you may press the menu button (
) to set the scan bandwidth
(100 MHz, 20 MHz and 10 MHz) and the pre-amplifier mode (-10 dB – attenuator, 0
dB – turned off, +6 dB – turned on). In addition, you may set the refresh speed in the
waterfall mode.
The scan bandwidth, as well as scan bounds may be quickly changed by pressing
the
(up),
(down),
(left) and
(right) keys. This parameters are
displayed at the bottom part of the screen. The
(OK) button will clear the screen.
Connect your antenna to the RP-SMA socket. Please notice that injecting high power
(such as an output of a wireless access point) into this socket may damage the tester.
