frequencies
Reference Frequency Accuracy
Initial Accuracy: Better than ± 10 ppm at 20 oC Stability: Better than ± 10 ppm over 10 oC to 30 oC Ageing: Better than ± 3 ppm per year
Phase Noise
Phase Noise: Typically -100dBc/Hz at 100kHz
offset at 500MHz
Resolution Bandwidth
RBW: Selectable 280 kHz or 15 kHz Video Filtering: Selectable independently of RBW setting
Markers
No. of Markers: One, Two (or None) Marker Resolution: 0.1 kHz at all frequencies Marker Accuracy: 1/320th of Span ± 0.1kHz plus reference frequency accuracy. Readout: The frequencies at the marker points and the frequency difference are
displayed
AMPLITUDE MEASUREMENT
Amplitude Range
Display Range: 80 dB Reference Level: Selectable as -20 dBm
or 0dBm Vertical Expansion: 40 dB window pan-able over
80 dB range
Amplitude Accuracy
Ref. Level Accuracy: Better than ± 1 dB
at 50MHz (20oC ± 5oC) Flatness: Better than ± 1.5 dB over
0.5MHz to 1300MHz Linearity: Better than ± 1 dB over 50dB
from reference level Noise Floor: Better than -90 dBm
average displayed noise floor (reference level = -20 dBm, RBW = 15 kHz)
Distortion and Spurii
3rd Order Intermod.: < –60dBc for two signals at 10dB below
reference level (500MHz and 501MHz) Harmonic: < –60dBc at 10dB below reference level (100MHz) 1st & 2nd Image: <– 55dBc, typically <– 60dBc Residual Spurii: Below noise floor
Markers
No. of Markers: One, Two (or None) Resolution: 0.1 dB Readout: The level at the marker points
and difference are displayed.
SWEEP
Sweep Method: Peak detection for 320
points per sweep. The amplitude and frequency of the peak level found
within each sub-span is stored (sub-span = span/320). Sweep Time: Set automatically by Span,
RBW and Video Filter. Sweep Modes: Normal (continuous),
Single, Peak Hold, Average (2 to 256). Sweep Control: Run and Stop buttons.
Peak-hold and Average are reset whenever Run is pressed.
DEMODULATION (Zero Span mode)
Demod. Modes: AM or FM Display: Carrier amplitude only
(horizontal line). Audio Out: 30 mW into 32
Ohm mono or stereo headphones, adjustable
volume, 3.5mm jack socket
SIGNAL INPUT Input
Connector: SMA connector, 50
Ohms VSWR: 1.5 : 1 typical Maximum Level: + 20 dBm
SUPPLIED ITEMS The PSA1301T incorporates a
Palm T|X handheld computer. The following items are also supplied: One SD (or MMC) memory card. USB linked card reader for use with PC. Universal mains adaptor/charger. USB lead (mini B plug to standard A plug). Multi-language “Read This First” leaflet. Printed users manual (English). Support CD containing multi-language manual and backup software.

DISPLAY
Display Type: 3.7
inch (9.4 cm) backlit TFT LCD,
480 x 320 pixels total, 16 bit colour,
touch screen. Trace Area: 300 x 320 pixels (high
resolution mode). Graticule: 8 x 10 divisions, light grey
graticule
with annotation (graticule selectable on or off). Displayed Points: 320 points per sweep
(peak detected). Live Trace: Dot-joined trace from
current
or held sweep using . Selectable on or off. Reference Trace: Stored trace either
recalled
from memory or copied directly from live trace.
Selectable on
or off. Resolution Modes: Selectable as High
Resolution
or Low Resolution. (In low resolution mode the trace area becomes
150 x 160
points where each point is a block
of 4 pixels. Only 160 sweep points
are displayed.
This mode is useful in situations where the display
could
otherwise be difficult to see - e.g. when
the instrument can not be
viewed at an optimum
distance.)
MEMORY STORAGE
Memory Type: Non volatile
Flash memory,
using removable SD or MMC cards
(one card supplied). Store Trace: Any number of traces can
be
stored under either default file names or user
entered file names.
Traces are stored as tables
of amplitude versus frequency and can be
imported into other programs, as well as
being recalled to the screen. Recall Trace: Recalls any stored trace
to the reference trace of the display. Store Set-up: Any number of instrument
set-ups
can be stored under either default file names
or user entered
file names. All settings
of the instrument are saved. Recall Set-up: Recalls any stored
set-up,
overwriting the existing settings of the instrument. Copy Screen: This function copies the whole
screen area to memory as a bit-map.
Any
number of screens can be stored under
either default file names or user
entered
file names.
Screen bit-maps can be viewed using
the handheld
picture viewing function,
or transferred to a PC for printing.
CONNECTORS
RF Input: Standard
SMA connector. DC Power: 1.3 mm power socket for
5.2V/1A external power source. USB: Mini USB connector which provides
direct access to the USB port of the handheld. Audio Out: 3.5 mm jack socket for
demodulated
audio out (accepts mono or stereo plugs).
POWER SOURCES
Battery Operation The spectrum analyzer and the handheld contain
their own rechargeable
battery packs.
The spectrum analyzer is controlled from
the handheld and
is turned off whenever
the spectrum analyzer program is exited,
or the
handheld is turned off.
Spectrum analyzer Battery Type: Ni-Mh 3.6V 700mA-hr (3 x
AAA) Battery Life: > 5 hours continuous
operation Recharge Time: < 4 hours from fully
discharged
Handheld Computer (Palm T|X) Battery Type: Li-ion 3V 1050mA-hr Battery Life: Typically 4 hours
continuous Recharge Time: < 4 hours from fully
discharged Auto Sleep Mode: To conserve
battery life,
the system can be set to automatically switch
into sleep
mode after a defined time from
the last key press. This can be set
between 5 mins and 60 mins (or never). Battery Status: Indicators for both
batteries.
AC Line Operation/Charging The PSA1301T can be operated
from mains power using the AC line adaptor
provided. This powers and recharges both the spectrum analyzer and the
handheld computer simultaneously. Voltage Range: 100V to 240V nominal
50Hz/60Hz
MECHANICAL

97mm wide x 47mm deep Weight: 495 grms total inc. Palm T|X. Tilt Stand: Built-in tilt stand for
bench
use which angles the unit at approx.
25 degrees to the horizontal. Stylus: Casing incorporates standard
Palm stylus.
