V34G3TX V.34 G3 signal transmission test
Details To test whether the specified V.34 G3 signal is transmitted.
By closing or opening the DC circuit in accordance with the setting
value, the specific G3 signal pattern is transmitted at the specified
transmission speed and modulation speed by the G3 signal
transmission function (V.34) of the modem.
Check this with the speaker.
A setting value other than 0 is indicated as a 3-digit integer (1st digit:
modulation speed, last 2 digits: transmission speed). A value other
than the specified numerical value is invalid.
Adj/set/operate method Enter the setting value, and then press Start key.
Caution Be sure to set the value back to 0 after the test.
