Query form:
CALCulate<n>:DERivative:POINts? [MINimum | MAXimum]
Response:
3 | 5 | .. | 129
If MINimum was specified, 3 is returned.
If MAXimum was specified, 129 is returned.
Query form:
CALCulate<n>:DERivative:STATe?
Response:
0 | 1
0 Differentiate function turned off.
1 Differentiate function turned on.
Description:
The CALC<n>:DER:POIN command specifies the width of the differentiate
window. The width of the differentiate window can be an odd number of points,
varying from 3 points to 129 points in increments of 2 points. The differentiate
window can be turned on with the CALCulate:DERivative:STATe command.
The CALC<n>:DER:STAT command switches the differentiate function on or off.
The result of the differentiate function is stored in M1_n for CALCulate1 and in
M2_n for CALCulate2 dependent on the input source CHn or Mi_n (n = 1, 2, 3, 4).
After a
*
RST command, the differentiate window width is 5 points and the
differentiate function is turned off.
Example:
Send → CALCulate:DERivative:POINts 21 The width becomes 21 points.
Send
→ CALCulate:DERivative:STATe ON Switches the differentiate
function on.
Front panel compliance:
The CALCulate1 and CALCulate2 commands use the MATH1 and MATH2
features of the CombiScope instrument.
