MF
Marker Frequency Output
The MF command returns the frequency level of the active marker to the controller, if the marker is on screen. If
both the delta marker and active marker are on screen, MF returns the frequency difference between the two
markers. (See MKDELTA and M3.)
The output can be formatted in any one of the four output formats. (Refer to FORMAT command, 01, 02, 03,
and 04.) However, do not use output format 04 for marker delta output, because sign information is lost.
A typical use of the MF command is shown in the sample program below.
10
ASSIGN @Sa to 718

PRINTER IS 701

OUTPUT @Sa;"FA 80MZ;FB 12OMZ;"
40
OUTPUT @Sa;"M2;El;"
50
OUTPTJT @Sa; "MF;"
60
ENTER @Sa;A

Line 30:
Selects start and stop frequencies.
Line 40:
Activates a normal marker and peak search.
Line 50:
Returns the frequency to the controller.
Line 60:
Assigns the frequency to variable A.
Line 70:
Prints the frequency amplitude.
An ENTER command must follow each output command, or output data is lost. For example, the following
program assigns only the marker amplitude to variable FT and the marker frequency value is lost.
OUTPUT 718;"MF;MA;"
