	SOM CODE : 3338/10 Model : 50-8150 COMPANY : HARVARD, ENGLAND. Student Oscillographs This versatile, compact, 2-Channel Student Oscillograph is available with curvilinear or rectilinear recording and features. Unlike the Modular Universal Oscillograph, see preceding pages, which supplies power to operate its ampli-fier interfaces, the Student Oscillograph requires freestanding AC or battery operated amplifi

Model : 50-8879	SOM CODE : D341/1 Model : 50-8879 COMPANY : HARVARD, ENGLAND. Brouchure AC/DC Preamplifier Interface : This is a general purpose differential Preamplifier for animal use only. - For ECG, EMG, ENG and EOG. - High gain, low noise and drift. - Step gain switch, x10, x50, x100, x200, x500, x1000. - AC/DC selector switch. - DC level control. There is a 6 position gain switch, an input selector for AC or DC coupled, a filter selector and a DC level control giving a maximum offset range of +4 volts. Input is via a 7-pin binder socket and output via edge connector into the Universal Oscilloscope or Interface Adapter.

Oscillographic Recording Applications 230V

Curvilinear Recording

Higher frequency response (70 Hz); greater trace width
Waveforms are commensurate with a curved trace
More suitable for teaching and demonstrations

Rectilinear Recording

Produces straight-line, pen tip travel that is easy to calibrate and measure
Reduced frequency response; (40 Hz) and pen travel
More suitable for analytical-type recordings, such as ECG

Pen Amplifier Module:

Maximum Gain 30 mV/cm

Input Impedance > 100 K½ (Single Ended)

Frequency Response:

Curvilinear DC to 70 Hz ±3 dB

Rectilinear DC to 40 Hz ±3 dB

Trace Width:

Curvilinear 5 cm (2 in)

Rectilinear 4 cm (1.6 in)

Dimensions, H x W x D:

2-Channel Recorders 195 x 508 x 205 mm (7-1/3 x 20 x 8 in)

4-Channel Recorders 195 x 508 x 305 mm (7-1/3 x 20 x 12 in)
