1.0 Introduction
1.1 Overview
The Praxsym CW Transmitter is a portable continuous wave test
source capable of transmitting test signals on two channels
simultaneously. The output from each channel can be enabled
independently. The output level can be adjusted between -10 dBm
and +12 dBm, in 0.1 dB steps.
Each channel contains four Setups . Setups allow the user to program
up to four saved output configurations (frequency, amplitude, and
channel spacing) per channel. The transmitter also contains Scan
Mode
which cycles through the
Setups
at an adjustable scan rate.
The transmitter frequency and output level for each channel can be
set from the touch keys on the front panel or from the touchscreen
display. The transmitter status can easily be monitored from the
backlit LCD display. The transmitter also contains a USB interface
enabling the user to control the transmitter remotely.
The transmitter can be powered using the internal 6 AA
rechargeable batteries for 6 hours of continuous operation or from
the AC/DC wall adapter included.
1.2 Functional Description
The transmitter will power on to a splash screen with the Praxsym
Logo, and immediately proceed to the main operation screen. The
previous settings from the last use will be retained. The transmitter
will not power on transmitting RF energy, though it may have been
powered off previously while transmitting. The transmitter may
safely be powered off in any state using the ON/OFF button.
The transmitter is configured with channel spacing of many common
wireless standards. Once the channel spacing is selected within the
Channel Setup menu, the step size may be adjusted from the main
operation screen. This function makes stepping across multiple
channels quick and easy during testing.
