To connect a signal to the oscilloscope
The 54615B is a two-channel, 500 MHz bandwidth, 1 GSa/s sample rate
oscilloscope with an external trigger input. The 54616Band 54616C are
two-channel, 500 MHz bandwidth, 2 GSa/s sample rate oscilloscopes with an
external trigger input. The input impedance of these oscilloscopes is
selectable – either 50Ω or 1 MΩ. The 50Ω mode matches 50Ω cables
commonly used in making high frequency measurements. This impedance
matching gives you the most accurate measurements since reflections are
minimized along the signal path. The 1 MΩ mode is for use with probes and
for general purpose measurements. The higher impedance minimizes the
loading effect of the oscilloscope on the circuit under test. In this exercise
you connect a signal to the channel 1 input.
To avoid damage to your new oscilloscope, make sure that the voltage level of
the signal you are using is less than or equal to 250 V (dc plus the peak ac).
For a complete list of the characteristics see chapter 5, "Performance
Characteristics."
CAUTION
Do not exceed 5 Vrms in 50Ω mode. When input protection is enabled in
50Ω mode, the 50Ω load will disconnect if greater than 5 Vrms is detected.
However the inputs could still be damaged, depending on the time constant
of the signal.
CAUTION
The 50Ω input protection mode only functions when the oscilloscope
is powered on.
• Use a cable or a probe to connect a signal to channel 1.
• The oscilloscope has automatic probe sensing . If you are using the
probes supplied with the oscilloscope, or other probes with probe
sensing, then the input impedance and probe attenuation factors will
be automatically set up by the oscilloscope when automatic probe
sensing is turned on. The default setting is to have automatic probe
sensing on. This is indicated by the selection of
Auto n under the Probe
softkey, where n is 1, 10, 20, or 100.
• If you are not using automatic probe sensing, then follow these next
two steps.
