1 Calculated coarse-tune DAC (0-4095)
2 Sampler harmonic number
3 Calculated sampler IF in Hz
4 Wide-band discriminator sensitivity factor
5 Actual frequency error in Hz on last count
6 Actual measured sampler IF in Hz
7 Actual coarse tune DAC number (0-4095)
8 Main coil sensitivity in number of bits per Hz
9 Actual fine tune DAC number (0-4095)
Spans >10 MHz, changes from sweep to sweep
Spans ≤10 MHz, relatively stable from sweep to
sweep
10 Actual extra-fine tune DAC number (0-4095)
11 Indicates which DAC is being adjusted in the
iteration process; coarse, fine, or extra-fine.
12 Last iterations of the extra-fine tun DAC.
Spans > 10 MHz, readout is in frequency
Spans ≤10 MHz, readout is DAC number
13 Extra-fine tune DAC iterations to get to correct
frequency (not present for spans ≤10 MHz)
14 Fine-tune DAC iterations to get to correct frequency
15 Counter timebase
16 Coarse-tune DAC iterations to get to correct
frequency
17 Drift calculation of marker count, a large difference
between the two LO counts indicates drift (only
present when MKR count is enabled)
18 Discriminator sensitivity factor
19 Sampling oscillator frequency in Hz
