Setting channel coupling
•
To apply a signal to Channel A. The signal being
tested is a sine signal that contains DC quantities.
•
Press [A] to select Channel A. Then press [F1] to set
A input to "ON".
•
Next press [F2] to select DC coupling. Both DC and
AC quantities of the signal being tested and input to
Channel A can pass through.
•
Press [F2] to select AC coupling. DC quantities of
the signal being tested and input to Channel A will be
intercepted. Only AC quantities can pass through.
•
Press [F2] to select ground coupling. The channel
input is now set to equivalent ground. The channel
input level appears on screen.
Note: In this mode, although waveform is not displayed,
the input signal remains connected to the channel circuit.
Setting the channel bandwidth limit
•
Applying a signal to Channel B. The signal being
tested is a signal stacked with high frequency
quantities.
•
Press [B] to turn Channel B on. Next press [F3] to
set channel bandwidth to full bandwidth. The signal
being measured can pass through even if it contains
high frequency quantities.
•
Press [F3] to set bandwidth limit to 20MHz. All high
frequency quantities higher than 20MHz in the signal
being tested will be limited.
