In FASTMODE, only one channel can be active, and it must be an analog channel.
Sampling can be as fast as 20ms/sample in this mode. FASTMODE is operational only for
sample rates from 50,000 sample/second to 5,000 samples/second.
Each probe has a minimum sample time, which is listed in the table below:
Probe Type
Analog probes
Sonic probes
Digital In/Out
Note: TrigTypes 0, 1, and 6 cannot be used with frequency measurements (operation 6) or with
period measurements (operation 5).
Note 2: TrigTypes 2, 3, 4, 5, and 6 cannot be used with count transition (operation 7).
Note 3: TrigTypes 1 and 6 cannot be used with FASTMODE sampling.
Note 4: While CBL 2 is waiting for TrigThresh, you can press the START/STOP to start sampling
immediately.
Command 4
This command sets up parameters to convert physical units measured by CBL 2 into a
more useful measurement unit such as Newtons or ¡C. It has six syntaxes.
Syntax: {4 , 0}
Clears the equation for all channels.
Syntax: {4 ,channel, M1}
Channel
1, 2, or 3
Sets unary equation; returns raw data for the channel.
Syntax: {4 ,channel, 1, N,K
Channel
1 = Sets CH 1
2 = Sets CH 2
3 = Sets CH 3
Sets up polynomial equation:
