Resolution:
This the smallest measurable value difference. This enables
all the generators start the same time and allows
users control their phase offset.
Note: for triangular square waveforms, smaller
frequency range usually specified.

BURST function
The BURST function can used generate pulse trains:
users define the train generation period and the number of
pulses the train./
GENERATORS
Theoretical Introduction:
Introduction domaine Generator
Definitions:
Signal waveforms
The generator can typically generate sine, triangle and
square waveforms, well their usual derivatives.
This function can controlled internally TTL signal
injected dedicated BNC connection
MASTER/SLAVE function:
This can used synchronize several 320s set in
a "cascade" arrangement.
PSK function: Value "Phase SKip" controlled internal
or external command signal.
Atflrh. mainly
depends the quality the oscillator used, for which
short-term and long-term stabilities are defined, expressed
in ppm (parts per million). For example, for the GX320: +/-
20ppm when F>10 kHz
SWEEP function:
The "SWEEP" function can used generate a
frequency sweep rising falling mode.
Frequency accuracy:
This corresponds the difference between the true value
of the signal's frequency and the value displayed.
The minimum frequency, which may just few mHz, is
used simulate slow phenomena (mechanical physical)
or control slaving (for example, triangular step profile).
It expressed digits and its absolute value depends on
the frequency range used.
Types modulation:
AM: Amplitude Modulation
FM: Frequency Modulation
FSK function: Frequency SKip controlled internally or
externally. This sweep can
be controlled the generator according linear or
logarithmic law the basis external sawtooth or
triangular signal applied via dedicated BNC connection.metrix.
It also provides means generating signal with very
large duty cycle briefpulse with long repetition period).

For the GX320, for example: 5-digit resolution MHz
corresponds kHz increment. The generator used the
"Master" supplies the other "Slave" instruments with the
clock (Clk) and synchronization signal (Ctrl).
