Setting Modes:Centre frequency plus Span, or Start plus Stop frequencies
Maximum Span:1299.85 MHz
Minimum Span:320 kHz, or Zero Span with demodulation
Setting Resolution:1 kHz at any frequency
Setting Accuracy:Reference Frequency Accuracy for Start, Stop & Centre (Zero-Span) frequencies
Reference Frequency Accuracy
Initial Accuracy:Better than ± 10 ppm at 20 °C
Stability:Better than ± 10 ppm over 10 °C to 30 °C
Ageing:Better than ± 3 ppm per year
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
Units:Selectable as dBm or dBuV
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 -93 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.
Limit Lines
Number of Limit Lines:Any number of lines can be defined with up to two displayed simultaneously.
Limit Line Editor:Tables of amplitude versus frequency with automatic straight line drawing between points.
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
Audio Filter:Selectable 3kHz low-pass filter
SIGNAL INPUT
Input Connector:SMA connector, 50 Ohms
VSWR:1.5 : 1 typical
Maximum Level:+ 20 dBm ( 127 dBuV); 15VDC
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
