Digitizing Signal Analyzers

Characteristics

Vertical System

Delta DC Volt Accuracy - ≤1% for an 8-division signal.

Vertical Resolution - 8 bits. Resolution can be increased to 14 bits with signal averaging or smoothing.

Bandwidth - To 1 GHz. Determined by the plug-in used.

Wide Dynamic Range - 1 mV/div to 10 V/div.

Horizontal System

Time Bases (Main and Window) Sweep Speeds - 50 ps/div to 100 s/div.

Record Duration - 512 ps to 1024 s in 1-2-5 sequence.

Time Base Accuracy -

+0.005%: -0.015%: 0 to 45 °C.

±0.005%: 20 to 30 °C.

Record Length - 512 to 32,768 pts (both single-shot and repetitive).

Sampling Rate - 2 GS/s max.

Main Record Positioning - The main record is positioned with respect to the main trigger point. At maximum pretrigger, all points except the last point in the main record precede the trigger point. At maximum posttrigger, all points except the first point in the main record follow the trigger point.

Window Time Base - The main record plus two window records may be acquired and displayed. The window records may be different lengths and can have a different time/div than the main record.

Window Record Positioning - The window records may be positioned with respect to their own trigger points on the main record. Window triggers may be delayed from the main trigger by time or events.

Multitrace Pan and Zoom - Multiple traces may be panned and zoomed simultaneously.

Display Interpolation - Zoomed waveforms can be displayed using either sin (x)/x or linear interpolation, or using a dots-only display without any interpolation.

Waveform Memory - More than 210 K points of volatile memory shared between acquired and stored waveforms.

Settings Memory - Nonvolatile memory for approximately five settings.
