Table 5-55 HarmSel – Harmonic Component Selection
Bitfield (16-bit WORD)
Note: H = Harmonic number. H0 = Fundamental frequency, H1 = 1 st
harmonic, H15 = 15
th
harmonic. Bit 0
(H0, the fundamental) is always set (1); therefore the fundamental frequency is always selected.
Tracking
Quality USINT Tracking quality value in 0.001% steps.
This is an advanced parameter used to fine-
tune tracking performance. Setting to 0 will use
the default value of 10 (0.01%).
Default: 10 (0.01% quality) 8
Intermod
F2 USINT The frequency number of the “F2” frequency to
use when computing intermodulation products.
One of the following values (ranging 0-5):
0 – No intermods requested.
1 – 5 – Fundamental frequency to use as the
F2 fundamental.
Default: 0 9
Intermod
Selection USINT The intermodulation products to produce. One
of the following values (0-3):
0 – No intermods requested.
1 – 1 “plus” and 1 “minus” product.
2 – 2 “plus” and 2 “minus” products.
3 – 3 “plus” and 3 “minus” products.
Default: 0 10
Tune USINT Frequency tuning control. This will determine
how the BDS locks onto a frequency. One of
the following values (ranging 0-2):
0 – Voltage channel used for fundamental
tracking.
1 – Current channel used for fundamental
tracking.
2 – Channel auto-select (default).
Default: 2 11
