Acquisition and waveform setupMXO 4 Series
109User Manual 1335.5337.02 ─ 07
If "Off screen capture" = On, all data is recorded, and the whole acquisition memory
can be used. The defined record length and segmentation settings are ignored. The
current number of recorded data points is shown in the progress bar when the bar is
green, or returned by the remote command ACQuire:ROLLmode:POINts?.
After stopping the acquisition, you can analyze the complete roll waveform, including
the invisible part:
●
Increase the "Time scale" to see a longer part of the waveform.
●
Scroll the waveform: tap and drag the waveform to the right.
If you want to save the waveform, disable "Off screen capture". When the needed data
is displayed, save the waveform. Thus, one record length is saved. With active "Off
screen capture", the amount of data cannot be limited.

6.1.5 Reference clock
Access: "Menu" > "Horizontal" > "Setup" tab > "Ref Clock"
The oven-controlled crystal oscillator (OCXO) produces a 10 MHz internal reference
signal with precise and stable frequency. You can output this clock signal for synchroni-
zation of other instruments. Conversely, you can also use an external 10 MHz refer-
ence signal. The input and output connectors for reference signals are on the rear
panel of the instrument.
Use external ref. clock
Enables the use of an external 10 MHz reference signal instead of the internal refer-
ence clock.
Remote command:
SENSe[:ROSCillator]:SOURce on page 539
Output 10 MHz ref. signal
Sends the internal reference clock signal to the Ref. Out connector.
If "Use external ref. clock" is enabled, the external reference signal is output instead of
the internal clock.
Remote command:
SENSe[:ROSCillator]:OUTPut[:ENABle] on page 539
6.2 Acquisition
Access: "Menu" > "Acquisition".
Acquisition settings define the processing of the captured samples in the instrument.
