Continuing, I wondered if I could implement a slider to control the Span of the P3’s display. This slider would have to implement the 'MN255;#SPN<D3>; command where D3 would be incremented from a low range of 000020 to an upper range of 002000 in increments of 100.
The P3 Programmers Guide gives the #SPN command as:
#SPN (Span; GET/SET)
SET/RSP format: #SPNxxxxxx; where xxxxxx is 000020-002000, the span in 100-Hz units. Example:
#SPN000500; sets the span to 50 kHz.
Apparently, the slider function truncates leading zeros and limits the value of <D3> to three digits.
+ Correct. If I understand correctly, you should instead use <D6>
