1 Safety Information
This instrument is Safety Class III according to IEC classification and has been designed to
meet the requirements of EN61010-1 (Safety Requirements for Electrical Equipment for
Measurement, Control and Laboratory Use).
This instrument has been tested in accordance with EN61010-1 and has been supplied in a
safe condition. This instruction manual contains some information and warnings which have to
be followed by the user to ensure safe operation and to retain the instrument in a safe
condition.
This instrument has been designed for indoor use in a Pollution Degree 2 environment in the
temperature range 5°C to 40°C, 20% - 80% RH (non-condensing). It may occasionally be
subjected to temperatures between +5° and -10°C without degradation of its safety. Do not

protection provided.
WARNING!
All accessible parts will be at the same voltage as the outer body of the SMA input socket. In
particular, note that the shells of both USB connectors are galvanically connected to the body of
the SMA input and will therefore be at earth ground potential when either USB port is connected
to a desktop PC. To maintain user safety under all other circumstances it is essential that the
input is not connected to a voltage above 30Vdc or 30Vrms with respect to earth ground which
is the limit of Safe Extra Low Voltage (SELV) by IEC definition.
The instrument shall be disconnected from all voltage sources before it is opened for any
adjustment, replacement, maintenance or repair. Any adjustment, maintenance and repair of
the opened instrument shall be carried out only by a skilled person in conjunction with the
Service Guide, see Maintenance section.

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 softkeys 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.

2.7 Battery and AC Line Operation
The instruments operate from an internal Li-ion polymer rechargeable battery which can provide
more than 8 hours of continuous operation (screen brightness dependent).
The battery is charged from the supplied 5V/2A charger which can recharge a fully discharged
battery in under 3 hours.
Only use the charger supplied to recharge the instrument.
The battery condition is indicated on the display; when it displays a single segment and
changes colour, expected battery life has fallen below 1 hour.
The instrument can be operated continuously from this external charger for bench-top
operation. When the battery is being charged, the LED next to the charging socket flashes.
When charging is complete, flashing ceases but the LED remains on while the charger is
connected.
2.8 Bench Stand and Screen Protector
The instrument is intended for both portable and bench-top applications.
It is supplied with the tilt stand folded away at the back of the instrument. This can be hinged
outwards to set an angle of about 40 degrees.
To protect the screen when in transit, the stand can be detached from the base and re-attached
on the top to act as a screen protector.
The stand is detached by flexing the sides until the locating lugs disengage from the body.
For outdoors use, the screen protector can be hinged upwards to form a sun shield which
improves the screen visibility in sun light.
When not required, it can be detached and stowed away on the back of the instrument.
2.9 Touch-screen and Hard Keys
The normal mode of operation of the instrument is by using the touch-screen keys at the bottom
of the display supplemented, when required, by the hard keys below the display.
The touch screen keys are normally operated by pressing firmly with the finger or thumb, or
gently with a finger nail. Alternatively they can be operated using the supplied stylus which
clips into the base of the instrument.
It is also possible to use the instrument without touching the screen at all, by using the five
‘navigator’ hard keys to operate each of the touch screen functions.
2.9.1 Using hard keys to navigate the touch-screen
Pressing the circular button marked ‘Navigate Screen’ changes the function of the five
Navigator keys from controlling the Markers to controlling the position of the on-screen key
highlight. The highlight position is shown by a change in the key colour to purple. Pressing the
centre button operates the selected key.
