2 General Information
2.1 About this Guide
This guide is comprised of the on-screen Help instructions available on the instrument itself,
plus some essential extra information, e.g. Safety. The on-screen Help is split into Topics
associated with each sub-menu of the five top-level menu groups; each Topic explains the
functions accessible via that sub-menu, see section 3.8.2 for details. In the on-screen Help the
Topic headings and function headings, which are context sensitive to the current menu
selection, are highlighted in green text for easy reference; in this guide the same headings are
shown shaded, e.g. Specifications and Capabilities, Frequency, etc.
The function headings shaded in this way are mostly the names of the menu and function soft-
keys as they appear on the screen. Note, however, that the keys of pop-up menus are
described within the associated function and do not have their own shaded heading; instead
they are identified in the text using ‘ ‘, e.g. ‘Set by Tab/Jog’. The hard keys are also identified
in this guide in the same way, e.g. ‘Navigate Screen’, ‘View’.
In this guide, as on the Help screen, > between key names indicates the sequence of keys
needed to select the function described.
2.2 Specifications and Capabilities
The PSA2702 and PSA1302 are portable spectrum analyzers incorporating a high resolution
colour TFT touch screen. They are sufficiently small and lightweight to be operated as a true
handheld instruments and have a battery life of more than eight hours from each charge.
Frequency can be set from 1MHz to 2700MHz or 1300MHz respectively to 1kHz resolution.
Span can be set between 0.270MHz and 2699MHz or 1299MHz. RBW is selectable as 1MHz,
280kHz or 15kHz. Frequency accuracy is 10ppm. Marker accuracy is 0.37% of span.
Level the on-screen amplitude range is 85dB with a reference level of -20dBm or 0dBm.
Vertical magnification to 1dB/div can be selected. Average noise floor is better than -95dBm at
-20dBm ref. level & 15kHz RBW (video filter on). Amplitude accuracy is better than +/-1dB at
50MHz with a level flatness better than +/-1.5dB from 1MHz to 2.7GHz or 1.3GHz.
Maximum input without damage is +20dBm or 50V dc.
Markers two markers are available with readout of frequency and level for each plus difference
values. Markers can be peak finding or peak tracking.
Sweep can be continuous or single. Sweep time is defined by the span and RBW.
Demodulation a zero span mode is available with AM or FM audio demodulation.
Traces there are three traces: live, view and reference. The live trace can be normal, peak hold,
or average (2 to 48 sweeps). Up to 999 traces can be stored internally.
Screen Images the whole screen can be stored as a bit-map. Up to 999 can be stored
internally.
Set-ups and Presets complete instrument set-ups can be stored (999 maximum). Presets are
available for complete re-setting and for commonly used frequency ranges.
Status and Help full instrument status can be displayed as can context sensitive help screens.
Power operation can be from batteries or mains power. Battery life depends on screen
brightness but is typically 8+ hours. Auto-off can be selected to switch off 5 to 60 mins after last
key press.
