Contradictions of Min Frequency and Max Frequency in DMM help file?

Dear sir, when i measurement the AC signals using PXI-4065 DMM, i should configure the min and max frequency of the signal with

niDMM_ConfigureACBandwidth(ViSession Instrument_Handle, ViReal64 AC_Minimum_Frequency_Hz, ViReal64 AC_Maximum_Frequency_Hz);

when i find the valid range of the two parameters, i find the contradictions in help file as follow:

what is the rang of the two parameters (Min Frequency and Max Frequency ) after all? Thank you very much for you help , sir .

Refer to the datasheet, you could find 10Hz - 100KHz is right.

This was reported to R&D (#180092) for further investigation. As indicated, the correct value can be found in the datasheet. I personally prefer the spec sheets, as that is the source for the datasheets. NI 4065 specifications. Thanks for the feedback!

Dear sxs707,

 

 

As I indicated, the valid range of NIDMM_ATTR_AC_MIN_FREQ is 10Hz-100KHz for NI 4065.

 

For detailed information, you could refer to the Datasheet or the Specification of NI 4065.

 

NI R&D is currently investigating the contradictions in Help Files you found, and a CAR (Corrective Action Request) #180092 has been created for this issue.

 

Thanks a lot for your feedback!
