Part 6: IEEE 488.2 Command Reference
PERSIST_SAT, PESA
Description
The PERSIST_SAT command sets the saturation level of the persistence color spectrum. The level is
specified in terms of percentage (PCT) of the total persistence data map population. A level of 100 PCT
corresponds to the color spectrum being spread across the entire depth of the persistence data map. At
lower values, the spectrum saturates (brightest value) at the specified percentage value. The unit PCT is
optional.
The response to the PERSIST_SAT? query indicates the saturation level of the persistence maps.
Command Syntax
PERSIST_SAT <trace>,<value>[...,<trace>,<value>]
<trace>:= C1 to Cn, F1 to Fn, TA to TD
<value>:= 0 to 100
Note: TA through TD are for backward compatibility. Although accepted, they are not returned by
queries.
Query Syntax
PERSIST_SAT?
Response Format
PERSIST_SAT <trace>,<value>
Example (GPIB)
The following instruction sets the saturation level of the persistence data map for channel 3 to 60%. This
means 60% of the data points are displayed with the color spectrum, and the remaining 40% saturated in
the brightest color:
