CENF (?) i
DS360 Ultra Low Distortion Function Generator
The NRCT command sets the Noise Rate Count to x. The NRCT? query returns
the current value of this parameter. x may range from 2 µs to 600 s.
If NRCT is set to a value lower than NBCT, NBCT is adjusted to NRCT/10; if
NRCT is set to a value more than 4 digits above NBCT, NBCT is adjusted to the
lowest allowable in that range (i.e. if NBCT=1ms, setting NRCT to 600s will
adjust NBCT to 100ms). An "ADJ BUR" message is displayed and bit 3 in the
DDS Status Byte is set in this case.
The BNDW command sets the white noise bandwidth to one of the following
frequencies:100 Hz, 200 Hz, 400 Hz, 800 Hz, 1.6 kHz, 3.2 kHz, 6.4 kHz, 12.8
kHz, 25.6 kHz, 51.2 kHz, 102.4 kHz. The value i is always expressed in Hz.
Values lower then 100 Hz will set BNDW to 100 Hz; all other values will be
rounded down.
The CENF command sets the white noise center frequency to i , which ranges
from 0 to 200kHz. The resolution of i is 200 Hz; all settings will be adjusted to i
modulo 200. CENF? query returns the currently set value.
