1.0 Introduction
1.1 Overview
The PST is complete, portable CW test source capable of transmitting
test signals in two bands simultaneously. The output from each band
can be enabled independently and level can be adjusted between –
10dBm and +10dBm in 0.1dB steps. Different transmitter models can
be configured to cover VHF, UHF, Cellular, GSM850, GSM900, iDEN,
PCS, GSM1800, GSM1900, UMTS bands.
The transmitter frequency and output level for each channel can be
set from the touch keys on the front panel. The transmitter status
can easily be monitored from the backlit LCD display. The touch-
screen on the display should be cared for properly. The transmitter
also contains an USB interface enabling the user to download spe-
cific transmitter configurations stored on a PC or control the transmit-
ter remotely.
The transmitter can be powered using the internal 6 AA recharge-
able batteries for 6 to 8 hours of continuous operation or from the
AC/DC wall adapter included.
1.2 Functional Description
The PST 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 PST may safely be powered off
in any state using the ON/OFF button.
The PST is configured with channel spacing of many common wire-
less 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 chan-
nels quick and easy during testing.
