1.2 Using this Manual - Cross References
This manual covers both the PSA6005 and PSA3605 spectrum analyzers. Within the text they
may be referred to jointly as PSAxx05 or PSA Series 5. 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
user to jump rapidly to the section referred to and then jump back to continue reading the
original section. (N.B. for hyperlink navigation within Acrobat Reader, enable “show all page
navigation tools” or use the keyboard shortcuts Alt+Right_Arrow and Alt+Left_Arrow).
1.3 Product Description and Capabilities
The PSA6005 and PSA3605 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 3 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 10MHz to 6000MHz (PSA6005) or 10MHz to 3600MHz (PSA3605). The
span can be set between 0.0270 MHz and 5990.000 MHz or 3590.000 MHz respectively with a
setting resolution of 100Hz. Start, stop or centre frequencies can be set to the same resolution.
The resolution bandwidth (RBW) is selectable between 300Hz and 10MHz in a 1:3:10
sequence or can be set to Auto. Video bandwidth (VBW) is similarly settable between 300Hz
and 10MHz or RBW tracking.
The on-screen amplitude range is approximately 84 dB with a reference level variable between
-40dBm and +20dBm. Amplitudes can alternatively be displayed in dBµV. Vertical
magnification down to 1dB/div can be selected. Average noise floor is typically better than
-120dBm at -40dBm reference level and 10 kHz RBW/VBW.
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 waveform
demodulation with variable timebase. Audio demodulation is provided via a built-in speaker.
Multiple detector modes include Positive Peak (default), Negative Peak, Alternate Peak, Lin or
Log Average, RMS, and Sample.
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 frequency counter can be used at the marker position with resolution down to 10Hz.
