1.2 Using this Manual - Cross References
This manual covers both the PSA2702 and PSA1302 spectrum analyzers. Within the text they
may be referred to jointly as PSAxx02 or PSA Series 2. The manual is also provided as a PDF
file on the accompanying CD. The manual includes many cross references which are shown as
follows - see section X.X. The Table of Contents is also fully hyperlinked.
Within a PDF file, the shaded number is a hyperlink to that section number which enables the

1.3 Product Description and Capabilities
The PSA2702 and PSA1302 are fully portable RF spectrum analyzers that incorporate a high
resolution colour TFT touch screen. They are sufficiently small and lightweight to be operated
as true handheld instruments and have a battery life of more than 8 hours from each charge.
As bench instruments they can be powered by the supplied ac-line adaptor/charger. They can
be set horizontally or vertically, or at an angle of about 40 degrees using the built-in tilt stand.
For field use, the stand can be moved to the top of the instrument to form a screen protector
and sun shield.
The frequency range is 1MHz to 2700MHz (PSA2702) or 1MHz to 1300MHz (PSA1302). The
span can be set between 0.270 MHz and 2699.000 MHz or 1299.000 MHz respectively with a
setting resolution of 1kHz. Start, stop or centre frequencies can be set to the same resolution.
The resolution bandwidth (RBW) is selectable as 1MHz, 280kHz or 15kHz.
The on-screen amplitude range is 85 dB with a reference level of -20dBm or 0dBm. Amplitudes
can alternatively be displayed in dBµV. Vertical magnification down to 1dB/div can be selected.
Average noise floor is better than -95dBm at -20dBm reference level and 15 kHz RBW (video
filter on).
Sweeps can be repeating or single shot, and the trace can be normal (over-write), peak hold or
average (2 to 48 sweeps). A zero span mode is available with AM or FM audio demodulation
via a built-in speaker.
Twin vertical marker lines are available giving a readout of frequency and amplitude together
with difference values. Markers can be manually positioned or automatically peak finding or
tracking.
A reference trace and a view trace can be displayed in addition to the live trace. Up to 999
traces can be stored to permanent memory for recall to the screen or for data export. 999
