{"product_id":"tektronix-ada400a-10831-1","title":"Tektronix ADA400A High-Gain Differential Preamplifier, 1MHz, 80V, 1Mohm\/55 pF, 0.1X\/1X\/10X\/100X","description":"\u003cp\u003eThe ADA400A Differential Preamplifier allows direct oscilloscope measurements\n  of very low amplitude voltages and signals which are not ground referenced. The\n  high impedance of both inputs eliminates the need to add additional ground points\n  in the DUT, thereby avoiding circulating currents which disturb the measurement\n  or the circuit. \u003c\/p\u003e\n\u003cp\u003eThe high gain and extremely high common mode rejection provide usable measurements\n  of voltages as low as 5 µV, even in high noise environments. Selectable\n  bandwidth limiting reduces normal mode noise from digital logic, switch mode\n  power supplies and line frequency sources. Adjustable differential offset allows\n  the user to null out transducer bridge bias and galvanic potential from the\n  test setup. An \"infinite impedance\" mode can be selected in the two\n  highest gain ranges allowing accurate measurements of signals with high source\n  impedance.\u003c\/p\u003e\n\u003cp\u003eThe ADA400A is powered directly from TDS400, TDS500, TDS600, TDS700, TDS5000,\n  TDS7000 (TekProbe), TDS7000 (TekConnect w\/TCA-1Meg) oscilloscopes.
