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).

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.

Store/Recall Limit Line: Any number of limit lines can be stored under either default file names or user entered file names

CONNECTORS

RF Input: Standard SMA connector.
DC Power: 1.3 mm power socket for 5.2V/1A external power source.
