Digital Noise:
Digital noise provides a random 0,1 pattern with
programmable sequence length.
Clock Range: 10 mHz to 100 MHz.
Sequence Length:
Standard: 2 n - 1, n = 6 to 16.
With Option 002: 2 n - 1, n = 6 to 17.
Comb:
Uniformly distributed frequency spectra within a
well-defined frequency band.
Start/Stop Range: 1 Hz to 10 MHz.
Number of Lobes: 3 to 256.
Signal-Plus-Noise, Signal-Plus-Comb:
Adds analog noise or comb to any standard or
arbitrary waveform with precise, controlled noise-to-
signal ratio.
N/S Ratio: 1% to 99% Vp-p.
Resolution: 1%.
Operational Modes
Continuous: The selected waveform is output
continuously at the programmed frequency.
Gated: The selected waveform is output
continuously at the programmed frequency
while the selected trigger signal is true.
Triggered: Upon transition of the selected trigger
from false to true, the number of cycles specified by
the count is output at the specified frequency. Burst
count is programmable from 1 to 1,048,575. (One
to 524,287 for waveform sequence operation.)
Sweep: Frequency sweep.
Triggering
Trigger Sources: 4 trigger sources: External TRIG
IN BNC, internal trigger generator, front panel
manual trigger key, and remote trigger command.
Trigger Level: The trigger level at the TRIG IN
BNC is programmable.
Range: -10 V to +10 V.
Trigger Slope: Positive or negative.
Internal Trigger Source
Range: 200 ns to 1000 s.
Resolution: 100 ns limited by 6 digits.
Sync Output
Sync output can be selected from among the
following 7 sources: waveform sync, trigger signal,
burst done, loop done, sweep marker,
position marker, pen lift.

100% modulation.
Signal Summing
External signals can be summed directly to the
Model 395 output through the SUM IN BNC.
Sweep
Standard and arbitrary waveforms can be swept.
Sweep Start/Stop
Range: 1 mHz to 20 MHz.
Resolution: 4 digits limited by 1 mHz.
Sweep Time
Range: 30 ms to 1000 s.
Resolution: 1 ms.
Sweep Types:
Sweep off, continuous, continuous with reverse,
triggered, triggered with reverse, triggered with
hold, triggered with hold and reverse, and manual.
Sweep Spacing:
Linear and logarithmic.
