Ping time[s] or Frame

numbers

Control

Occurrence number of Stop condition selection. The variable is

displayed in accordance with “Stop condition” value.

If Ping Time is set to 0, the Ping session continues until “Stop

Ping” button is pressed.

Reset MIB counters on

start

Control

Selection to erase MIB objects 06h (PHY Data) and 07h (DL

Data) before starting the Ping session.

Start and Stop buttons

Start Ping

Control

Button to start the Ping session

Stop Ping

Control

Button to force the Ping session before the Stop condition is

achieved.

Received frame features

Slave address

Indicator

Slave address field of the last received frame (i.e., first byte of

the DL_DataIndication or DL_SnifferIndication received by the

ST7580)

Data

Indicator Payload data (without Slave address field) of the received frame

Length

Indicator Length (in bytes) of the Payload data, calculated by the GUI

Modulation

Indicator Signal modulation of the received frame

PGA code

Indicator PGA value on the received frame

SNR value

Indicator SNR estimation (over UW reception) performed by ST7580

Frequency channel

Indicator RX channel (high or low) on the received frame

Ping session activity and results

Time count [s]

Indicator

Number of seconds elapsed during Ping session. Active if “Stop

condition” is equal to time only, hidden otherwise.

Received OK

Indicator

Number of received frames with correct CRC (i.e.

DL_DataIndication notified by the ST7580) and Slave address

field equal to the value set in “Slave Address” control.

These frames are re-transmitted, in accordance with Ping

session rules.

RX Wrong Address

Indicator

Number of received frames with correct CRC (i.e.

DL_DataIndication notified by the ST7580) and Slave address

field not equal to the value set in “Slave Address” control.

RX Wrong CRC

Indicator

Number of received frames with wrong CRC (i.e.

DL_SnifferIndication notified by the ST7580).

Frames sent

Indicator

Number of frames successfully transmitted by the Slave,

updated by the GUI during Ping session execution

Ping active

Indicator

LED displaying the Ping session activity:

-Green when Ping session is active;

-Red when Ping session is not active.
