: Used to select the frequency range in the frequency mode. Press RESET to
select the 10MHz frequency range. Press again to select the 100MHz frequency
range and press a third time for the 1300MHz frequency range.
: This button attenuates the input signal. Press it to attenuate the input signal
sensitivity by a factor of 20.
: Low-pass filter button. When the button is pressed in:
- 100KHz, -3dB
- 150KHz, -3dB at ATTN condition
: BNC input connector for Channel A. Provide a signal to input A to measure
frequencies from 10Hz to100MHz and also periods and totals.
: BNC input connector for Channel B. Provide a signal to input B to measure
frequencies from 100MHz~1300MHz.
: displays the measured value
