- Provides the selected
form atthe main
output.
S/N Signal-to-Noise operation adds noise to a selected
signal of constant amplitude. The signal-to-noise ratio
is variable from 0 to
+60 dB.
N/S Noise-to-Signal operation adds a selected signal
to a constant amplitude noise. The noise-to-signal ratio
is variable from 0 to
+60 dB.
FM Frequency Modulation - Provides random modu-
lation of the frequency of the generator. The S/N
- N/S
(dB) ratio control also controls the amount of fre-
quency deviation.
NOTE
When noise is added to the signal output,
specifications apply up to 200
kHz and
the square wave rise time is dera ted by
a factor of 10. In the clock range of
1.6 MHz, the maximum calibrated
signal-
to-noise ratio is 30 dB
Temperature
All specifications listed, except stability, are for
25’C
*5’C. For operation from O°C to 55’C, derate all
specifications by factor of 2.

NOTE
All specifications apply for frequencies
obtained when dial is between 0.
1 and
2.0 and at 10 V p-p in to a 50 ohm load.
It is possible to stop the generator from
oscillating by applying a negative VCG
voltage when the dial is already set at
minimum frequency. VCG inputs up to
30 V will not permanently damage the
ins trumen t.
