Magnification (Mag)

Lower center

Text indicates the mag setting. If mag is on, the text appears in yellow to indicate

 

 

that the signal is not being displayed in the normal time scale.

 

 

 

Sweep rate

Lower center

Text indicates the selected sweep rate.

 

 

 

Closed caption presence

Upper left

When the instrument detects the presence of a closed caption signal, CC is

 

 

displayed on the screen.

 

 

 

Timecode

Upper left

Text indicates the type of timecode (VITC or ATC) and the decoded time. A

 

 

semicolon between the seconds readout and the frame readout indicates that the

 

 

timecode is of the “drop-frame” variety. If no timecode is present, no text appears.

 

 

 

Ancillary data

Upper left

Indicates the presence of ancillary data packets in the video stream, excluding

 

 

packets for embedded audio and RP165 EDH. Possible messages are as follows:

 

 

Blank -- No ancillary data packets present.

 

 

Anc Present -- Indicates that one or more ancillary data packets are present, and

 

 

that no parity or checksum errors were detected.

 

 

Anc Error -- Indicates that one or more ancillary data packets are present, and that

 

 

one or more parity or checksum errors were detected.

overshoot, rise time, fall time, and rise-fall time delta.

 

 

 

Gamut error

Top center

When gamut errors occur, the readout (if enabled) will display either “RGB,” “Y+C,”

 

 

or “Lum” for RGB, Composite, or Luminance gamut errors, respectively.

 

 

 

Current date and time

displayed field and line number. It also indicates in which portion of the video signal

 

 

the selected line occurs.

 

 

 

Sample

Upper right

When Line Select is active and Sample is selected, text displays the selected

 

 

sample number, followed by the portion of the video signal that the sample is in,

 

 

such as Y, Cb, Cr, EAV, HB, or SAV.
