Grass SD9E Stimulator
Grass SD9E Medical Therapeutic/Laboratory Electronic Nerve Stimulator (TENS/EMS) unit. 120vac 50/60hz powered, dual-isolated outputs.
SPECIFICATIONS:
Delay Function 0.02 to 200 msec (4 decades)<br> Separates PREPULSE SYNC OUT pulse from the stimulus <br>
pulse, used to set refractory time interval for TWIN <br>
PULSE operation<p>
Synchronous Outputs: PREPULSE SYNC OUT precedes the<br>
stimulus pulse as selected by the variable delay<br>
PULSE SYNC OUT occurs at the end of delay period which<br>
is coincident with the onset of the stimulus pulse<p>
Frequency 0.2 to 200 PPS (3 decades)<br>
Duration 0.02 to 200 msec (4 decades)<br>
Output Volts (Peak) 0.1 to 100 volts (3 decades)<br>
Output Impedance ²1 kohm<br>
Maximum Power Out 2.5 watts peak<br>
Sync Input and Output +5 volts, TTL compatible<br>
Output Isolation Circuit: Built-in to allow recording<br>
with the stimulator at the preparation site with minimum<br>
artifact. Output voltage not referred to ground. Output<br>
polarity selectable.<br>
Biphasic Output: Can be selected to reduce electrode<br> polarization and ion transfer<br>
Monitor Lamp Flashes with each stimulus pulse<br>
Accuracy ±10% or better for all parameters<br>
Maximum Power 30 watts at 110 volts, 50/60 Hz<br>
Typical Power is 5 watts<br>
Physical Size 9.5" W x 5.25" H x 5.5" D <br>(24.1 cm x 13.3 cm x 14 cm)<br>
Weight 3.7 lbs. (1.6 kg)<br>
