Part 6: IEEE 488.2 Command Reference
SEQUENCE, SEQ
Description
The SEQUENCE command sets the conditions for the sequence mode acquisition. The response to the
SEQUENCE? query gives the conditions for the sequence mode acquisition.
When Sequence mode is turned by using this command, SMART memory is automatically enabled and
the memory length is set to the user-supplied <max_size> value. The argument <max_size> can be
expressed either as numeric fixed point, exponential, or using standard suffixes.
Sequence mode cannot be used at the same time as random interleaved sampling (RIS). If RIS is on, the
command SEQ ON turns RIS off.
Refer to the product datasheet at teledynelecroy.com for Sequence mode specifications.
Command Syntax
SEQUENCE <mode>[,<number segments>[,<max_size>]]
<mode> : = {OFF, ON}
<number segments> : = <any valid value>
<max_size> : = <any valid value, e.g., 10e+3 , 5K, 1M, etc.>
Note: The oscilloscope adapts the requested <max_size> to the closest valid value.
Query Syntax
SEQUENCE?
Response Format
SEQUENCE <mode>,<number segments>,<max_size>
Example (GPIB)
The following instruction sets the segment count to 43, the maximum segment size to 250 samples, and
turns the sequence mode on:
CMD$="SEQ ON,43,250": CALL IBWRT(SCOPE%,CMD$)
