Comments Maximum Samples: The total number of readings is limited to at most 16,777,215 for the 4-channel E1564A Digitizer and 33,554,431 for the

2-channel E1563A Digitizer, depending on the amount of memory on the card. The following describes the limits with the different memory options.

If a number greater than the maximum is set, the digitizer goes to continuous mode and SAMPle:COUNt? returns 0. If no readings are pulled out while running, the digitizer will stop at MAX -1 + 250 (MAX for FIFO and CACHE).

Pre-Trigger Sample Required: One pre-trigger sample is required to get the above maximums. The maximum is one less if pre-trigger count is zero.

Executable when initiated: NO

Coupled command: NO

Reset (*RST) condition: All channels set to 1 sample

SAMPle:COUNt?

SAMPle:COUNt? [MIN MAX] returns the number of samples each channel will make. The number of samples returned is common to all channels.

SAMPle[:IMMediate]

SAMPle[:IMMediate] is generally used only when the sample source is HOLD to take a single reading when the digitizer is in the wait-for-sample state.

SAMPLe:PRETrigger:COUNt

SAMPle:PRETrigger:COUNt <count> MIN MAX sets the number of pretriggers (number of readings that will occur before the trigger event occurs). The count is common to all channels.
