2. Using This Manual & Meaning of Terms
Cross References within this Manual
This manual is also provided as multi-language PDF files. The manual includes many cross references
which are shown as follows - see section X.X.
Within a PDF file, t he boxed number is a hyperlink to that section number, thus enabling the user to
jump rapidly the section referred to and t hen jump back to continue reading the text.
TTi
TTi is used throughout this manual as the abbreviation for Thurlby Thandar Instruments Ltd.
Handheld Computer and PDA
Devices such as the Palm T
|
X are commonly described as handheld computers, palmtop comput er s or
PDAs (personal digital assistants). The term ‘handheld computer ’ is used throughout t his m anual.
PSA1301/2701
This is used to describe the spectrum analyzer unit excluding the Palm T
|
X handheld computer.
PSA1301/2701T
This is used to describe the complete spectrum analyzer unit including the Palm T
|
X handheld computer.
3. Initial Operations
3.1. Charging the Batteries
It is probable that the batteries will be discharged when the product is r eceived. Conseq uently the first
action should be to charge the unit using the supplied mains adapt or. To fully charge t he bat teries it
should be left charging for 4 hour s.
3.2. Initialising the Palm T|X
If the battery has been fully discharged, the Palm T|X handheld computer will have to be re-initialised
before the spectrum analyzer can be used. Details of how t o r e-initialise it are given in section 14.
Note: The PSA1301/2701 spectrum analyzer adaptor does not require any manual initialisation.
5
3.3. Software provided by Palm on CD
The software and support informat ion pr ovided by Palm assumes that you will want to link your Palm T|X
to a personal computer on a regular basis. The Palm “Read t his First” manual instructs you to load the
CD software immediately as part of the initial set up.
Users of the PSA1301/2701T do not need to do this unless they choose to. TTi recommends that user s
read the relevant sections of the Palm documentation and consider their own use of the product before
deciding whether to install to Palm software.
Note: Do NOT make a USB connection between the PSA1301/2701T (or the Palm T
|
X) and a PC
unless the Palm software has already been installed.
3.4. Linking to a Personal Computer
The following applies to both the PSA-T and the Palm T|X by itself. (The mini USB connection on the
side of the spectrum analyzer is a direct throug h connec t ion t o t he USB port of the Palm T|X).
Although the Palm T|X was designed to be USB connected to a PC using Palm Desktop soft ware, this
software is now obsolete and will not work with 64-bit operating systems.
It is NOT necessary ever to link the PSA1301/2701T to a personal computer. It is a self contained
instrument which can perform its primary f unc t ion of RF spectrum analysis without linkage to other
devices. TTi provides a USB linked memory card reader in order that PSAnalyzer files can be
transferred to a PC where this is required.
4. First Use of the Spectrum Analyzer
After charging the batt er y and initialising the Palm T|X, it will then be possible to use the Spectrum
Analyzer by launching the PSAnalyzer application.
TTi recommends that you should read this manual in full before using the PSA1301/2701T.
However, if immediate use of the spect r um analyzer is requir ed, t he following procedure can be
used to start making measurem ents quickly.
4.1. Quick Sta rt Guide
Before commencing - the batteries m us t have been charged and the Palm T|X initialised as
described in sections 3.1 and 14
respectively.
1. Connect the signal to be measured - connect signal to the SMA connector at the top of t he
spectrum analyzer. The maximum allowable signal without damage is +20dBm (+127dBuV or
2.2 V rms). The maximum measurable signal is 0dBm (+ 107dBuV or 223 m V r m s). If there is a
possibility of the signal exceeding these levels, add suitable in-line attenuation.
2. Launch the PSAnalyzer application - enter the Applications screen (by pressing the Home key
once or twice). Press the PSAnalyzer icon on the touch screen of the Palm T|X,
(the touch screen can be operated with a fingertip or the stylus of t he Palm T|X).
3. Select the Mode Menu - press the on-s cr een Mode key.
6
4. Select Preset – press the Preset key.
This sets Quick Menu mode, Span maximum, Attenuation on, Highest RBW, Sweep mode
normal, Marker M1 on at the centre of the sweep.
5. Observe the Sweep - the sweep time will be slow because of the wide span.
6. Adjust the Attenuator – If the peak signal is below the –20dBm gr aticule line, press the Attenuator
On/Off key to toggle the attenuator to Off t hus incr eas ing the sensitivity.
7. Move the Marker – use the 5-way navigator to move the mark er to the area of interest and position it
at the centre of the signals t o be obs er ved.
8. Centre the Sweep -.pr es s t he Set C= M1 key to re-centre the sweep around the new marker position
(Note: the span will be reduced to the maximum that can be achieved with the new centre
frequency)
9. Zoom the Span – Press the Zoom-In key successively to create a narrower span that shows more
detail of the signals of interest.
The above procedure should be sufficient to get start ed. Thereafter adjustments can be made to sweep
parameters, attenuator, resolution bandwidth, etc. as may be appropriate to the signals being obser ved.
Basic on-screen help information for every menu is available by pressing the Help hard k ey. Some
general information regar ding the capabilities of the unit is available from the Info key on the Exit menu.
4.2. Detailed Operating G uide
To fully understand the operat ion of the PSA1301/2701T and PSAnalyzer, it is neces sar y to r ead this
manual.
From an operating point of view, the key sections are “Using the PSAnalyzer Application” section18
,
“The PSAnalyzer Menu System” section 19, and “PSAnalyzer Operating Techniques ” sec t ion 20.
5. Product Description and Capabilities
Brief Summary
The PSA-T series (PSA1301T and PSA2701T) are fully portable spectrum analyzers incorporating a
handheld computer (a Palm T
|
X). They are sufficiently small and lightweight to be operated as a
handheld instrument and has a typical battery life of four hours from each charg e. Alternatively they can
be used as bench instruments using the supplied mains adaptor/char ger. They can be set horizontally or
vertically, or at an angle of about 25 degrees using t he built -in tilt stand.
The spectrum analyzer has a frequency rang e of 0.15 MHz to 1300 MHz (PSA1301T) or 1MHz to
2700MHz (PSA2701T). The span can be set anywhere between 0.320 MHz and 1299.850 MHz
(PSA1301T) or 2699.000 MHz (PSA2701T) with a resolution of 1kHz. Start, stop or centre frequencies
can be set to the same resolution. The resolution bandwidth is selectable as 280 kHz or 15 kHz
(PSA1301T) or 1 MHz, 280 kHz or 15 kHz (PSA2701T).
7
The on-screen amplitude range is 80 dB with a refer ence level of -20dBm or 0dBm. Amplitudes can
alternatively be displayed in dBµV. Vertical magnification to 5dB/div can be selected. Average noise
floor is better than -90dBm at -20dBm reference level and 15 kHz RBW.
Sweeps can be continuous, single shot, peak hold or average (2 to 256 sweeps). Sweep time is defined
by the span and resolution bandwidth, and varies between 0.1 sec and 30 sec. A zero span mode is
available with AM or FM audio demodulation.
Twin vertical marker lines are available giving a readout of frequency and amplitude to a resolution of 0.1
kHz and 0.1 dB. Markers can be manually positioned or automatically peak finding and t r ac king.
A reference trace can be displayed in addition to the live trace. Limit lines can also be created and
displayed.
The graticule is fully controllable. Any number of traces can be stored to perm anent m emory for recall to
the screen or for data export. Limit lines, inst rument set-ups and complete screen bitmaps can also be
stored.
Battery life depends upon screen brightness, but is around four hours of cont inuous oper at ion from a
charge. To conserve the batt er y, auto-sleep mode can be selected whereby the unit turns off
automatically after a defined period from the last key press. All data is retained when off.
Pressing the Help hard key brings up a help screen relevant to the current menu position.
Full details of the product capabilities are given with the Specification section 6
and Using the
PSAnalyzer Application section 18 onwards.
