MM4005 FT — Set output frequency
Usage  IMM  PGM  MIP
Syntax FTnn
Parameters
Description nn
[float] — Desired frequency.
Range nn — 0 and 0.01 to 5000.
Units nn
— Hz.
Defaults nn Missing: 0.
Out of range: Error D.
Non-increment: Rounded to nearest frequency increment (see table).
Description This command controls the output signal on pin 24 of the 25-pin auxiliary
connector. The nn parameter represents the frequency of the output sig-
nal. Setting nn to 0 disables the frequency generator. The output has an
open collector configuration and a frequency range and resolution shown
in the following table:
F (Hz) ∆F (Hz)
(Output frequency) (Frequency resolution)
0.01 - 20 0.001
20 - 250 0.010
250 - 500 0.020
500 - 1000 0.100
1000 - 2500 0.500
2500 - 5000 1.000
NOTE
For the hardware definition of the frequency generator port, please see
Appendix B, Connector Pinouts, Auxiliary Connector.
Returns
None.
Errors D — Unauthorized execution.
Rel. Commands None.
Example
FT218.24
| Set an output frequency of 218.240 Hz on pin 24 of the auxiliary con-
nector.
