Magnification Views - In addition to the main timebase, the CSA8000 supports two magnification views. These magnifications are independently acquired using separate timebase settings.

Maximum Trigger Rate - 200 kHz.

Trigger System

Trigger Sources -
External direct trigger.
External pre-scaled trigger.
Internal clock trigger: Internally connected to direct trigger.
Clock recovery triggers (from optical sampling modules) - internally connected to pre-scaled trigger.

Trigger Sensitivity -
External direct trigger output:

Pre-selected trigger input:

Jitter -
Short-term jitter optimized mode:

Locked to 10 MHz reference:

Internal Clock - Adjustable from 25 to 200 kHz (drives TDR, internal clock output and calibrator).

Cursors - Dot, vertical bar and horizontal bar cursors.

Waveform Processing

Up to eight math waveforms can be defined and displayed using the following math functions: Add, Subtract, Multiply, Divide, Average, Differentiate, Exponentiate, Integrate, Natural Log, Log, Magnitude, Min, Max, Square Root and Filter.
In addition, measurement values can be utilized as scalars in math waveform definitions.

Mask Testing - In addition to user-defined masks, the following predefined masks are built-in:
