1004 Hz TONE (1004 Hz)
To select a continuous 1004 Hz sine wave output, press the left SEND key so that 1004
Hz indicator is lighted. The signal generator then outputs a continuous 1004 Hz sine
wave. Figure 9-3 shows the 1004Hz data display and the level parameter. Level is
adjustable after being selected with the PARAMeter SELect key.
This function is useful for tests which require that a hold tone be sent to a remotely-
located AM5(e) Classic. The level should be set so that at least –40 dBm is received at
the remote-end.
The AM5(e) receive circuits provide a notch filter and light the HOLD TONE indicator
when one of the MEASURE Functions that requires a received 1004 Hz tone is selected
(S/N RATIO, IMP N W/T, NOISE W/T). For details refer to sub-sections 6.4, 6.6, and
6.7.
