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 OK key.
Caution
Be sure to set the value back to 0 after the test.
