Probing/Level

Probing - Choose from One Differential and Two Single Ended values.

Level - Provide a desired voltage level for your decode. Enter a value using your preferred input control
method. Additional information on using the touch screen controls can be found in the Dialog Area (on
page 196)
.

Hysteresis (V) - Provide a desired voltage level for the Hysteresis.

Protocol Setup

Speed-mode - Choose from Low (26Mbps), Medium (1248Mbps), and High (1456Mbps).

IQ Period - Choose from 2G(541.66kHz), 3G(7.68MHz), LTE(1.4MHz), LTE(3MHz), LTE(5MHz),
LTE(10MHz), LTE(15MHz), and LTE(20MHz).

IQ Format - Choose from Standard and Custom values. Custom rescales I & Q by a factor of 16.

RF Path - Choose from Main and Diversity values. This control extracts I & Q data from an LC packet. LC
packets labeled ID5 are for Main selections and ID6 are for Diversity selections.

DigRF v4 Decode Trace Annotations

Like all trace annotations, DigRF v4 Decode annotations are rectangular shadings used to highlight messages on
decoded waveforms for easy viewing.

Tip: Data packets (or messages) on properly decoded protocol signals can be viewed using Serial Decode Trace
Annotations
(on page 18), the Protocol Results Table (on page 19), and/or by Searching for Messages (on
page 21)
(Types and Subtypes). Using these tools together provides fast insight to your data. See Serial Decode
Trace Annotations
(on page 18) for more information.

Messages shown as annotations, table columns, and search types for most protocols are classified into Frames,
Errors, Unknown, or Grouped Primitives specific to the protocol. Sub Types then further classify each main
message type into more protocol-specific messages.

Decode annotations unique to DigRF v4 include the following (some annotations are not shown in the screen-
shot):

DigRF v4 Decode Annotations

Time - Duration measured from the trigger location.

Synch

SoF - Start of Frame

LCID - Logical Channel Identifier

CRI - Cyclic Running Index

TxRx - Transmit or Receive

WordName - User-defined column. Define/customize this column by modifying the DigRFv4_B10I.xml file
as described in Customizing WordName and Comment Definitions (on page 128).
