2.7.2.3 Rapid block mode example 2: using aggregation
#define MAX_SAMPLES 1000
Set up the device up as usual.
Open the device
Channels
Trigger
Number of memory segments (this should be equal or more than the number of
captures required)
// set the number of waveforms to 100
ps3000aSetNoOfCaptures (handle, 100);
pParameter = false;
ps3000aRunBlock
(
handle,
0, //noOfPreTriggerSamples,
1000000, // noOfPostTriggerSamples,
1, // timebase to be used,
1, // not used
&timeIndisposedMs,
1, // segment index
lpReady,
&pParameter
);
Comments: the set-up for running the device is exactly the same whether or not
aggregation will be used when you retrieve the samples.
for (int segment = 10; segment < 20; segment++)
{for (int c = PS3000A_CHANNEL_A; c <= PS3000A_CHANNEL_D; c++)
{
ps3000aSetDataBuffers
(
handle,
c,
&bufferMax[c],
&bufferMin[c]
MAX_SAMPLES
Segment,
PS3000A_RATIO_MODE_AGGREGATE
);
}
Comments: since only one waveform will be retrieved at a time, you only need to set
up one pair of buffers; one for the maximum samples and one for the minimum samples.
Again, the buffer sizes are 1000 samples.
