Getting Started
Digital channels connector
The MSO option includes a 17-channel flying lead set logic probe, an MSO cable,
and a calibration fixture.
GEN OUT
Waveform generator signals are output to this BNC connnector. See "Waveform
Generator" on page 43.
AUX OUT
This output signal is selected by the Infiniium oscilloscope application's
Calibration Output dialog box. It can be a DC level, the probe compensation signal
(a square wave used to adjust compensated passive probes), the trigger out
signal, or a demo signal.
10 MHz REF IN (50 Ω )
The 10 MHz REF IN (50 Ω ) BNC connector is used to synchronize the oscilloscope's
horizontal timebase system to a reference clock that you provide.
To use an external reference clock, connect the external clock to the 10 MHz REF
IN (50 Ω ) BNC connector; then, in the Infiniium oscilloscope application's
Horizontal dialog box ( Setup > Horizontal... ), enable the External 10 MHz Reference
Clock .
10 MHz REF OUT (50 Ω )
You can use the 10 MHz REF OUT (50 Ω ) BNC connector to send the oscilloscope's
10 MHz reference clock output signal to another instrument's reference clock
input.
The output has these characteristics:
•
Amplitude into 50 Ω (internal or external timebase reference selected): 1.65 ±0.05 Vpp
(8.3 ±0.3 dBm) sine wave
CAUTION
Maximum input voltage at 10 MHz REF IN input
The clock you provide must meet the following specifications:
•
Input frequency lock range: 10 MHz ±20 ppm
•
Amplitude, sine wave input: 356 mVpp (-5 dBm) min to 5 Vpp (+18 dBm) max
•
Amplitude, square wave input: 285 mVpp min to 4 Vpp max
•
Input impedance: 50 Ω (typical)
