5.6.01 Dual Harmonic Setup Menu

CH2 ANALOG OUTPUT
X2% (2.5V fs)
The CH2 connector on the rear panel will output a voltage related to the X2%fs
front panel display as follows:-
X2%
+300
+100
0
-100
-300
The minimum step time per point for oscillator amplitude and frequency sweeps in
FAST mode is 140 ms.
Pressing the Previous Menu key returns control to the Configuration Menu.
This completes the description of the dual reference mode menus.
The dual harmonic mode allows the model 7280 to measure signals, applied to the
signal input, at two different harmonics of the reference frequency simultaneously.
The reference may be either externally supplied or derived from the internal
oscillator. During dual harmonic mode operation, some of the control and display
menus differ from those used for single reference mode, so these are described in the
following sections. The remaining menus operate in the same way as in single
reference mode, as already described in section 5.3.
When the Configuration menu is displayed, pressing the Dual Harmonic key
activates the dual harmonic mode. While the instrument switches to this mode, the
Dual Harmonic Setup menu is displayed, as shown in figure 5-47.
