What does Duty, Dwell, Pulse & Converge mean?

What does Duty, Dwell, Pulse and Converge mean?

When Rife researchers discuss frequencies to use, in order to treat disorders, they often quote Duty, Dwell, Pulse and Converge values.

For example:

duty 71.5
dwell 180
pulse 1 60 2900
converge 1 .03125

These values come from a a program that runs on an Atelier Robin F100 style (F165 in latest version) square wave frequency generator.




It is a well known pad device and some people use it to control plasma devices. Its programming language is the preeminent language for controlling frequency devices.

You can download the manual from here and see how it works.

Many researches quote these number without identifing where the numbers came from and this leads to some people being confused about these numbers.



Duty

Sets the duty for the main frequency. The duty is the on time versus cycle time of the main frequency pulse (on time/cycle time)*100.

Argument units: d in percentage

Examples:
duty 50 # 50% on, 50% offduty 10 # 10% on, 90% off
Note that the software will translate the requested duty to a value that the device can produce. The generator specifications indicate what range of duty cycle it can produce on each channel. Some channels, like channel c, have a fixed duty cycle. In that case, the duty cycle command is ignored.

Dwell

Sets the default dwell (duration) value. The dwell is the length of time the requested frequency will be generated. The dwell value specified will be applied to any subsequent frequency in the program file up to the next dwell or cdwell instruction.

Argument units: s in seconds
Range: s: 0.0 to 20000000.0

Examples:
dwell 120 # Run for 2 minutesdwell 0.5 # Run for half a seconddwell .75 # Run for 3/4 second

Pulse

Runs a frequency in the background on a channel not being programmed Pulsing is a signal applied to the programmed frequency. In digital terms, if the programmed frequency = F, the pulse frequency = P and the output of the device = OUT, then OUT = F AND P . This command is also used to turn pulsing off as: "pulse 0 0". This command is similar to the backfreq frequency except that it automatically selects the channel to run the background frequency on. If channel a is the current program channel, pulse will run on channel b, if channel b or c is the current program channel, pulse will run on channel a.

Argument units:

f in Hz
d in percentage on

Examples:
pulse 4 50 # Pulse at 4hz, 50% dutypulse 5000 10 # Pulse at 5khz, 10% dutypulse 0 0 # Turn pulsing off
Note: Pulse is off by default

Converge

converge r s
Useful if you are not certain of the exact frequency to produce but want to produce frequencies in the neighborhood of a set of known frequencies.

Similar to the fuzz command except that frequencies are run below and above the center frequency alternating with each step. How wide the sweeps are is specified with the "r" argument in two different ways

In the first way, r is the number of hertz below and above the frequency. Each frequency f in the program between this statement and the next converge or fuzz command will produce frequencies f-r to f+r with step s and alternating above and below the center frequency at every step.

In the second way, r is a percentage. The sweep will be from f-(r/100*f) to f+(r/100*f) with steps s. To use this command, you must add a "%" immediately after the number.

For multiple frequencies, converge only needs to be specified once, before the list of frequencies.

Converge can be turned off with the command: converge 0 0

Examples:
dwell 11
converge 5 1
727
# is equivalent to running in this order:
# 722, 732, 723, 731, 724,
# 730, 725, 729, 726, 728,
# 727 for 1 second each
#
dwell 18
converge 2% .5
100
# is equivalent to running: 98, 102,
# 98.5, 101.5, 99, 101, 99.5
# 100.5 100 for 2 seconds each
#
converge 0 0
# turns off converge for the following
# frequency commands
Note: When using the converge command, the dwell time is computed by dividing the default dwell time by the number of steps in the fuzz. For example: dwell 100
converge 5 1
100
# Sets default dwell to 100 seconds
# Converge has 11 steps:95,105,96,104,97,103,98,102,99,101,100
# Each frequency will run for dwell/11=9.09 seconds

The original example therefore has the following meaning:

Main duty cycle 71.5%
Frequencies will run for 180 seconds total (there's only one frequency in this program)
Each frequency will be pulsed/gated at 1Hz at a pulse duty cycle of 60%.

Converge 1 .03125 means that this frequency is actually composed of 2*(1/0.03125) + 1 or 65 steps. The first frequency to run will be 2900 + 1, then 2900 - 1, then 2900 + 1-.03125, then 2900 - 1+.03125, then 2900 + 1-.06250, then 2900 - 1+.06250, etc, toggling above and below the target frequency, getting ever closer (by 0.03125 every step), "zeroing in" on the frequency. The function generator calculates how long each of these 65 steps must run so the frequency is complete within the dwell time of 180 seconds.
