The voltage pre-magnifiers are low noise amplifiers, process amplifiers, 50 hz traps, high-through filters
Low-through filters, output amplifiers and output levels, input control of circuits, magnifying multiple control circuits, trap control circuits
High- and low-through filter cut-off frequency control circuits and power circuits. The rationale is outlined below:
Control the path selection single-end input (a input), or double, according to measurement needs to be measured for microvoltage signals
End input (a-b differential input). First from the low noise amplifier, then from the main amplifier
Users choose whether to go through the 50hz trap as needed. Leaching below or above pending mail via high- and low-throughput filters
No. Noise and jamming signals. It is then amplified by an output amplifier. The magnification of the whole amplifier, from the panel
Digital switch controls that change the magnification multiplier for low noise amplifiers, primary amplifiers and output amplifiers. Zoom in multiple by panel
On the right. For example: serial number 6, magnified by 1k. The cut-off frequency for high-to-high, low-to-low filters is also due
Digital switch controls on panels, e. G. High-through filter number 2 with a cut-off frequency of 100hz; low-through filter number
4 the cut-off frequency is 1khz. The zoomed signal is output from the output cable plugin q9 of the panel。
