DESCRIPTION:

Tektronix 5A21N Differential Amplifier Instruction Service Manual 

Introduction :

The 5A21N Differential Amplifier is a high-gain differential amplifier plug-in unit for use with Tektronix 5100-series oscilloscopes, and permits the measurement of current signals as well as voltage signals. The unit features high sensitivity with direct-coupled inputs (50 pV/DIV or 0.5 mA/DIV), and has a high common-mode rejection ratio .

• An illuminated knob skirt provides deflection factor readout. The unit has a bandwidth capability of DC to one megahertz, and a front-panel pushbutton switch allows reduction of the upper bandwidth limit, thus increasing the signal-to-noise ratio for low-frequency applications .
• This instrument will meet the performance requirements listed in Table 1-1 following complete calibration as given in Section 4. The following electrical characteristics apply over an ambient temperature range of 0 °C to +50°C. In this manual the word Volts/Div or division refers to major graticule division .
