The MultiAmp Calibrator generates sine- and square-wave signals for use in
the functional testing of bioelectric signal amplifiers. It has both
high- and low-level outputs. The high-level output (1V or 5V
peak-to-peak) is intended to connect to the amplifier via a signal
attenuator or directly to the input of an A/D converter. The low-level
output (50 or 250 microvolts peak-to-peak) is intended to connect directly
to the amplifier input via an appropriate interface cable. |

Portable EEG electrode impedance measurement system.
10 Hz, 1 kOhm - 20 kOhm. Note that this meter is useful only with passive
electrodes, and cannot be used with active electrodes.

 2 cc earphone coupler (ER-11-2)
For use in coupling insert earphones to a 1 inch microphone, as with the
RS-DS-LM Digital Sound Level Meter). |
 Digital sound level meter (RS-DS-LM)
Use this handy calibrator to measure sound pressure
level from auditory stimulus sources for purposes of calibration.
Combine with 2 cc coupler above to simulate impedance at the ear with insert
earphones. 50 to 126 dB SPL, 1 inch mic input, A/C weighting,
non ANSI.

 EMF field tester
This handy field tester can be used to locate
sources of electromagnetic interference in the lab environment. Use
the field tester to get an initial estimate of the level of interference in
the environment before deciding to install an expensive shielded room. |
