• Manufacturer: Fluke

Specifications of FLUKE-284

• Frequency: 1 mHz to 10 MHz
• Equipment Type: Waveform Generator
• Lead Free Status / Rohs Status: Lead free / RoHS Compliant

Operating modes
Continuous
Waveform runs continuously.
Triggered burst
Each active edge of the trigger signal will produce one burst
of the waveform.
Gated
Waveform will run while the Gate signal is true and stop while false.
Sweep
Frequency sweep capability is provided for both standard and
arbitrary wave forms. Arbitrary waveforms are expanded or con-
densed to exactly 4096 points and DDS techniques are used to
perform the sweep.

Multi channel sweep
(multi-channel units only)
Any number of channels may be swept simul-
taneously. Amplitude, Offset and Waveform can
be set independently for each channel. For Fluke
280 units the sweep parameters will be the
same for all channels. For Fluke 290 units the
sweep parameters can be set independently for
each channel.
Tone switching
Capability provided for both standard and
arbitrary waveforms. Arbitrary wave forms are
expanded or condensed to exactly 4096 points
and DDS techniques are used to allow instanta-
neous frequency switching.

modes
Tone switching modes:
Gated: The tone is output while the trigger
signal is true and stopped, at the end of the
current waveform cycle, while the trigger
signal is false. The next tone is output
when the trigger signal is true again.
Triggered: The tone is output when the
trigger signal goes true and the next tone is
output, at the end of the current waveform
cycle, when the trigger signal goes true
again.
FSK: The tone is output when the trigger
signal goes true and the next tone is
output, immediately, when the trigger
signal goes true again. Using 2 channels
with their outputs summed together it is
possible to generate DTMF test signals.
Trigger generator: Internal source 0.005
Hz to 100 kHz square wave adjustable in
10 us steps. 3-digit resolution. Available for
external use from any SYNC OUT socket.
