TDS7104 & TDS7054 Service Manual
H Move the signal to CH 1, and set the Trigger S OURCE to CH 1.
H Press PUSH TO SET 50%.
H SettheVerticalSCALEofCH1,CH2,CH3,andCH4to50 mV.
H Set the test signal amplitude for about five divisions on screen. Now
fine adjust the generator output until the CH 1 Amplitude readout
indicates the amplitude is 250 mV. Readout may fluctuate around
250 mV.
H Remove the 2X attenuator.
H Repeat steps k through q.
H Connect the 2X attenuator to CH 1.
H Move the coaxial cable to CH 1, and set the Trigger SOURCE to
CH 1.
H SettheVerticalSCALEofCH1,CH2,CH3,andCH4to10 mV.
H Set the test signal amplitude for about five divisions on screen. Now
fine adjust the generator output until the CH 1 Amplitude readout
indicates the amplitude is 50 mV. Readout may fluctuate around
50 mV.
H Remove the 2X attenuator.
H Repeat steps a through g.
4. Disconnect the hookup: Disconnect the cable from the generator output at
the input connector of the channel.
