COMMAND REFERENCE 4 - 33
CALCulate<n>:FEED
Syntax:
CALCulate<n>:FEED "<trace_name>"
Note: The parameter "<trace_name>" is <string_data>.
Therefore, it may be specified between single quotes as
well, i.e., ’<trace_name>’.
<n> [1] | 2
<trace_name> A trace name which is a predefined
<acquisition_trace> or <memory_trace>.
<acquisition_trace> CH1 | CH2 | CH3 | CH4
<memory_trace> Mi_1 | Mi_2 | Mi_3 | Mi_4
Note: - i = 1 .. 8 (standard memory)
- i = 9 .. 50 (extended memory)
Query form:
CALCulate<n>:FEED?
Response:
"CHn" | "Mi_n"
Note: - n = 1 .. 4 (n=1 .. 2 for PM33x0B)
- i = 1 .. 8 (standard memory)
- i = 9 .. 50 (extended memory)
Description:
The CALCulate:FEED command controls the source for the calculate function.
The trace specified by <trace_name> is selected as source for the calculate
block. After a
*
RST command, CH1 becomes the source for the CALCulate1 and
CALCulate2 functions.
Limitations:
•
A channel must be ON before it can be selected.
•
An empty trace may not be used as source in a CALCulate command.
•
M1_i is not allowed as source for a CALCulate1 command.
•
M2_i is not allowed as source for a CALCulate2 command.
Example:
Send
→ CALCulate2:FEED "CH3" Channel 3 becomes the source for MATH2.
Send
→ CALCulate:FEED ’M8_4’ M8_4 becomes the source for MATH1.
Front panel compliance:
The CALCulate1 and CALCulate2 commands use the MATH1 and MATH2
features of the CombiScope instrument.
