Channel Descriptor Box
Channel trace descriptor boxes correspond to analog signal inputs. They show Vertical settings and any
Vertical cursor readouts: (clockwise from top left) Trace Number (Cx), Pre-Processing List (summarizes
changes from default state), Coupling, Gain Setting, Offset Setting, and Averaging Sweeps Count.
Codes are used to indicate pre-processing that has been applied to the input. The codes have a long and
short form. When several processes are in effect, the short form is used.
Preprocessing Symbols on Descriptor Boxes
Pre-Processing Type Long Form Short Form
Inversion INV I
Deskew DSQ DQ
Coupling DC50, DC1M or AC1M D50, D1M, or A1
Ground GND G
Bandwidth Limiting BWL B
Similar descriptor boxes appear for zoom (Zx), math (Fx), and memory (Mx) traces. These descriptor boxes
show any Horizontal scaling that differs from the signal Timebase.
Digital Descriptor Box
Digital descriptor boxes (WS3K-MSO) appear whenever a digital line group is enabled. They
are named Digital1 and Digital2 corresponding to one of the two line groups.They show the
number of digital lines in the group, digital sample rate, and digital memory.
Timebase Descriptor Box
The TimeBase descriptor box shows: (clockwise from top right) Trigger Delay (position),
Time/div, Sample Rate, Number of Samples, and Sampling Mode (blank when in real-time
mode).
Trigger Descriptor Box
Trigger descriptor box shows: (clockwise from top right) Trigger Source and Coupling,
Trigger Level (V), Slope, Trigger Type, Trigger Mode.
Setup information for Horizontal cursors, including the time
between cursors and the frequency, is shown beneath the TimeBase and
Trigger descriptor boxes. See the Cursors section for more information.
