g) signal with dial pulse, tone (DTMF) or MF h)

Frequency: 200 Hz to 19,999 Hz in 1 Hz steps. Frequency may be entered directly via the keypad or stepped up or down in 10 Hz steps or auto repeat steps of 100 Hz (4 steps/ second) for fast frequency slewing. Frequencies are crystal-controlled and accurate to +.5 Hz. Level: + 10.0 dBm to, -50.0 dBm in . I dB steps. Level may be entered directly via the keypad or stepped up or down in .1 dB steps or auto-repeat steps of 1.0 dB (4 steps/second) for fast level slewing.

Impedences:

Terminate: 600 or 900Ohm.
