1 General
Master-9 is a 9-channel pulse stimulator designed for nerve and muscle stimulation procedures
and a broad range of neurophysiological stimulation requirements.
1.1 Outputs
Each channel delivers repetitive, single, train or twin outputs. The outputs can be set to
monophasic and biphasic pulses and ramp outputs.
All channels can be operated independently of each other, or synchronized to produce simple and
complex pulse patterns.
You can use some channels to stimulate your preparation, while using other channels to trigger
other instruments (oscilloscope, PC, etc.) in synchronization with the stimulation.
1.2 Paradigms (chapter 11)
Master-9 stores nine user-preprogrammed experiments (paradigms). Each paradigm can use all
nine channels. You can easily switch your setup to the selected paradigm.
This feature is very useful in the following cases:
When the current protocol requires modifications during the course of the experiment. You
can preset the modifications in different paradigms and then switch between the experiments
easily.
When several users of a setup run different experiments. Each user can retrieve his specific
settings from the Master-9 memory.
All parameters of the 9 paradigms are stored in the memory even after the power is switched off.
1.3 Controlling the Master-9
You can control the Master-9 as follows:
1. As a standalone unit – via its touch screen
2. Via your PC – using our MASTER-9 CONTROL software
3. From within your own application – using the Master-9 SDK
1. Controlling Master-9 via the touchscreen (chapter 3):
The touchscreen (TS) on the front panel displays all modes of operation and time parameters,
as well as a table of the internal connections between channels. You can set the channel
parameters by touching the TS with your finger or any stylus pen or standard pen. Do not
touch the screen with ink or sharp tools!
