Premodulated (2 Pole)
Premodulated Current is a medium
frequency waveform. Current comes out
of one channel (only two electrodes).
A bipolar technique in which the two
frequencies are “mixed” inside the machine
prior to tissue delivery.
WAVEFORM SPECIFICATIONS
PARAMETERS
Carrier
Frequency
Carrier frequency is the
base frequency of the
alternating current.
Beat
Frequency
(High & Low)
Occurs when two
waveforms are in and out
of phases. The difference
between the two
frequencies produces the
modulated effect
(i.e. Beat H. of 4000 and
Beat L. of 4150 will
yield a 150 pps beat
frequency).
Cycle Time
Cycle time refers to the
time that the current is
On and Off (in seconds).
Example: For a cycle
time of 10/50, the current
will be flowing for 10
seconds and resting for
50 seconds.
Ramp Time
Ramp time is used to
set a gradual increase in
intensity during the
“on-time”. Ramps occur
at the beginning and
ending of a cycle.
