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.

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).

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
