If the amplitude of either Tone1 or Tone 2 is set outside of these limits, the unit will
beep, display the message “Adj 2tA” (adjusting 2Tone Amplitude) and modify the other
Tone amplitude so it is within the allowable range.
Relative Amplitude
Amplitude may be set in dB relative to a user defined value for all functions except 2-
Tone. To make the currently displayed value the relative value, press [REL]. To set the
value in dB (relative to the previously entered rel’d value), type the new value, followed
by the [dB] key. The “rel’d” value can be displayed in Vrms, dBm or dBV, without
changing the amplitude, by pressing the appropriate key. To display the “rel’d” value in
Vpp, press [SHIFT][REL] which will display the Vpp value briefly. Pressing the [REL]
key a second time takes the amplitude out of relative mode, as does entering a value in
Vrms, dBm or dBV.
Unbalanced Output Amplitude
The amplitude range is limited by the DC offset, since
(V

For a DC offset of zero, the amplitude range for each function is shown in the tables
below for different source impedance’s.
