WP01 VAVEFORM PROCESSING OPTION
10.1 Processing Capabilities
The WP01 Waveform Processing Option includes an additional
0.5 megabytes random access memory for accumulation, computation and
waveform buffers. This allows accumulation of averaged waveforms of
32000 data points in 32-blt form.
All waveform processing occurs through the waveforms E and F which may
be displayed on the screen by pressing the corresponding FUNCTION E, F
(48) push button. Whenever the FUNCTION E or F trace or an expansion
one or both of these traces (in EXPAND A or B) is turned ON, the
corresponding waveform processing is executed. Whenever the trace (and
its expansion) is turned OFF, the processing is suspended. This is true
even for remote control. The display can be turned off by remote
control in order to gain speed (command SCREEN OFF, Section 7.6.3);
however, even in this case the corresponding function trace must be
turned ON although nothing is displayed on the screen.
FUNCTIONS E and F are waveforms that exist independently of (i.e. in
addition to) the acquisition memories of CHANNELS 1 and 2 and of the
reference memories C and D. On the display, they are treated similarly
to memories C and D, i.e. the vertical display gain and the vertical
position can be modified, but not the horizontal position and the time
magnifier. Of course, they can be expanded by redefining the source
waveform of the traces EXPAND A or B.
Two different processing functions can be executed simultaneously.
FUNCTIONs E and F may be read by remote control just like the other
traces, with the additional option of reading 16-bit data values, and,
as with Channels 1 or 2, they may be stored in reference memories C or
D by pressing the STORE push button (I). Waveform processing functions
operate on one or two source waveforms which may be CHANNEL i or 2,
Memory C or D. FUNCTION F may also operate on FUNCTION E. Since the
results of the processing functions can be stored in the reference
memories, and since FUNCTIONS E and F may operate on these reference
memories (and F may operate on E), chaining of operations is possible.
Waveform processing can take an appreciable execution time when
operating on many data points. The user has the option of reducing the
execution time by limiting the number of data points which are used in
the computation.
