Frequency Resolution Spike Software

[flo]

Hi all,

when I do measurements with a RBW and VBW of 1 Hz or 0.3Hz the exported CSV file contains multiple (up to 17) datapoints for one frequency.

For Example:
0.000001, -133.8737
0.000001, -130.2981
0.000001, -129.1483
0.000001, -129.0257
0.000001, -129.3259
0.000001, -129.8784
0.000001, -129.3519
0.000001, -129.7823
0.000002, -129.0396
0.000002, -127.3051
0.000002, -127.0553
0.000002, -127.3738
0.000002, -127.9133
0.000002, -129.3536
0.000002, -127.8060
0.000002, -126.7642
0.000002, -127.1276
0.000002, -127.7227
0.000002, -128.4352
0.000002, -130.2650
0.000002, -130.7844
0.000002, -131.2248
0.000002, -131.7348
0.000002, -131.5789
0.000002, -132.9086
0.000002, -132.7957
0.000003, -133.8598

Is this just a limitation of the saved CSV file or cant Spike save frequencies with a resolution less than 1 Hz.
Attached a example measurement with 0.3Hz RBW and VBW.

Hi Flo,

It looks like we use the default print resolution which is 6 digits after the decimal. I can look to change this in a future release to print more digits after the decimal, or change the units to Hz.

I apologize for the inconvenience.

Hello, Andrew,

Thank you very much for your answer. I look forward to the next software release.
