telephones will allow you to talk with both hands free. Multimeters
can also help. See Lab Accessories.
- Consider using electronic mail to convey technical information
or technical support questions. We will keep your electronic communications
on-line indefinitely; we archive any hardcopy.
- We will endeavor to correct any product design defect in
which the product does not conform to our printed specifications,
when you report the problem, whilst you own the product. Send
sample data in machine readable form (see
Sending Us Data)
so that your situation can be reproduced.
Include an ASCII file containing an explanation of the data. Do not
send batch files.
- We will clarify any ambiguity, error, or omission in the
reference manual for any product. We request that queries be submitted
via electronic mail.

Product Technical Support.
- The plans provide technical support in the use of the product.
Support does not extend to consultation in specific applications,
experiment design, statistical methods, or products not purchased
from us.
- Please submit queries via electronic mail where appropriate,
otherwise, via telephone.
- Our telephone technical support hours are 1 PM to 3:30 PM
Eastern Time, weekdays.

- Custom designed: Built to your specification, for
research in EEG, EMG, ECG, EOG, SCL, SCR, FP, EP, respiration, temperature,
oximetry, and somatic activity. Electro-cap electrode caps may be
purchased with your bioamp.
- Conformity: Meets AAMI/ANSI standard ES-1, 2.1.
- Tolerance: Handles high electrode impedances because
of high common-mode rejection, optical isolation, and high input impedance.
LEDs indicate which channel has excessive impedance.
- Expandability: Expandable from 8 channels to over
512 channels.
- Portability: Briefcase-sized bioamp weighs only 4
to 28 pounds; has recirculating/rechargable battery power.
- Ultra energy efficiency: Uses 1.2 W for a 32 channel
system; this is the power consumed by a two D-cell flashlight!
- Truly isolated: 4 kV peak optical and magnetic isolation
barriers using state-of-the-art 1990's technologies.
- High impedance: Greater than 1 gigaohms;
(ECT protected inputs are available).
- Low noise: The typical noise levels, referred to input,
are approx. 0.2 µVrms at 100 Hz bandwidth
and approx. 1.6 µVrms at 10 kHz bandwidth.
- Negligible crosstalk between channels: Separation
is better than 10000:1 (greater than 80 dB), worst case, at full output.
- High common-mode rejection: Typical CMRR at 50 Hz
or 60 Hz is greater than 112 dB. This reduces the requirement for
special screen-rooms and other low-EMI environments and signal-damaging
50 Hz or 60 Hz notch filters.
- Customer selected gains: Select gains from 100 to
200,000. A quad-gain option is available.
- Customer selected bandwidths: Select high-pass down
to 0.01 Hz and low-pass up to 10 kHz. A quad low-pass and quad high-pass
option is available. Butterworth 2-pole filter response is standard;
other types and 4-poles are optional.
- DC option: DC response is available with one of three
methods of baseline recovery: a local reset, a remote reset, and a
periodic reset with local control of the interval period. Unlike amplifiers
from other vendors, DC response does not increase noise!
- Rapid recovery: Special circuitry in each channel
automatically reduces "lead-off" recovery time to just a few
seconds when the high-pass filter is 0.01 Hz and even faster when
higher high-pass filter frequencies are selected.
- QRS (ECG) blanking: An option is available to eliminate
contamination of EMG.
- Self-monitoring: LED monitors on each channel provide
a continuous display of the integrity of each electrode connection.
Impedance measurements are optional with the bioamps; if the LED warning
is off then accurate data are being acquired.
- Remote monitoring: A TTL trouble-flag, available through
the output cable, indicates that a failure has occurred. Monitors
all electrodes, internal power circuits, and the battery.
- Internal calibration source: Precision calibration
signals facilitate accuracy and performance tests; sine, square, and
pulse waveforms are available.
- High reliability and serviceability: We use gold contacts
in all IC sockets and at all critical connections for stability and
reliability; all ICs are in sockets for serviceability.

and calibration signal control.

resistant version available for harsh tropical field use.

- Vertical Interval Time Code (VITC) generators
place a computer readable time code on each frame prior to recording.
The time code is placed above the video image and is not visible.
VITC readers read the time code off each frame during playback and
send it to the computer. A user selected number is also placed on
each frame for identifying a videotape.
- Any color camera may be used with these VITC generators.
Do not use inexpensive black & white surveillance cameras because
they have nonstandard sync pulses.
- Two camera protocols require some camera synchronization
solution:
- Use two VITC generator boards and recording VCRs; videotapes
will be synchronized.
- Use a split-screen special effects generator and a single
VCR; images are synchronized, but each image occupies only half the
screen.
- Use a clap board or tone (ideally on channel two) and the
audio tone detector; place VITC on a copy of the original tape and
the clap board will synchronize the copies.
