3.10.4 Reading data from trace memory
The TRACe? query allows you to read the contents from one of the following trace
memory registers:
An acquisition trace from one of the input channels (CH1 to CH4).
Previously stored trace data from one of the memory registers (M1 to M8 or to
M50). This can be either an acquisition trace or a trace of constant values
(refer to section 3.10.3).
The result of a post processing function; CALCulate1 in M1 and CALCulate2
in M2 (refer to section 3.9 "Post processing").
PROGRAM EXAMPLE:
*****
’Read the actual channel 1 trace into trace1$ and the filtered
’channel 1 trace into trace2$.
*****
DIM trace1 AS STRING
*
2000
Dimensions trace buffer 1
DIM trace2 AS STRING
*
2000
Dimensions trace buffer 2
CALL Send(0, 8, "TRACe? CH1", 1)
Requests for channel 1 trace
CALL Receive(0, 8, trace1$, 256)
Reads channel 1 trace into trace1$
CALL Send(0, 8, "CALCulate:FEED ’CH1’", 1)
Input source = CH1
CALL Send(0, 8, "CALCulate:FILTer:FREQuency:STATe ON", 1)
Enables frequency filtering; the filtered channel 1 trace is stored in M1_1
.
CALL Send(0, 8, "TRACe? M1_1", 1)
Requests for M1_1 trace
CALL Receive(0, 8, trace2$, 256)
Reads M1_1 trace into trace2$
