4.4.5.3 Arbitrary Waveforms - Frequency 1Period
Forarbitrary waveforms, set the "frequency"
as
sample
dock
or waveform "frequency."
See figure 4-30.
Sample
Selecting F3 "sample" programs the sample
dock
of
the Arb waveform in frequency
or
period units; maximum sample
dock
frequency is
lOO
MHz. Also, sample
dock
resolution is 4 digits.
Waveform
Selecting F7,
"waveform"
(sample
rate
divided by
number
of
waveform points.
Minimum sample
dock
period is
lO.OO
ns,
When waveform frequency or period is selected, the Model 395 checks the number
of
points
in
the Arb waveform and
"programs"
the sample
dock
frequency need
to
produce that waveform and the waveform frequency or period.
ARBITRARY FREQUENCY:
50.00 MHz

4.4.5.4 Sequence - Frequency/Period
Selecting Sequence Frequency will only
allow
you
to
program
the
sample
dock
(frequency
or
period). Maximum
dock
frequency is
lOO
MHz, and minimum
dock
period is
lO
ns.
4.4.5.5 Pulse 1Pulse Train Period
Selecting pulse Frequency programs the pulse period. Minimum pulse period is 100 ns.
Selecting pulse train Frequency programs the pulse train period. Minimum period for
pulse train is 100 ns.
4.4.5.6 Noise Clock
Frequency, while running a noise waveform, programs the sample
dock
(to 100 MHz)
for the noise waveform. Plus, the frequency screen for analog noise, comb, signal pulse
noise, and signal plus comb adjusts the startand stop Bandwidth ranges. Signal plus
noise
and
signal plus comb frequency screens allow the programming
of
the signal
frequency.
For detaiIs onnoise setup and operation, refer to paragraph4.4.12, Standard Waveforms.
