channel. The frequency of the driven channel is also measured to
determine the proper frequency for the bandpass filter.
The upper left section of the display shows the crosstalk reading,
which is the amplitude of the non-driven channel. The upper left soft
key selects the display units. The usual absolute and relative
amplitude units are available, plus ‘dB’, which displays the amplitude
difference, in decibels, between the driven channel and the
non-driven channel.
The upper center section of the display shows the amplitude of the
alternate channel. Pressing the upper center soft key selects among
the usual absolute and relative amplitude units.
The upper right section of the display shows the frequency of the
alternate (driven) channel. This frequency is used to tune the
bandpass filter. The upper right soft key turns the reading on or off.
Pressing the INPUT A button will select input A for the main
(non-driven) channel, and input B for the alternate (driven) channel.
It will also turn generator channel B on and channel A off. Pressing
the INPUT B button will select input B for the main (non-driven)
channel, and input A for the alternate (driven) channel. It will also
turn generator channel A on and channel B off.
The signal on the driven channel must be at least 8 mV for proper
functioning of the frequency counter for bandpass tuning. If it is not,
both the XTALK reading and the frequency reading will read ‘Low’.
No fixed filters are available.
