SECTION 4 OPERATING INSTRUCTIONS
4.5.4 Level Continuous Mode
This signal generator employs a mechanical attenuator to vary the output level. For this reason, momentary signal
interruptions and spike noise may be produced when you vary the output level.
Therefore, you select the level continuous mode in the cases where such momentary signal interruptions and spike
noise pose particular problems in the measurements you are conducting.
When you activate the level continuous mode, the operation of the mechanical attenuator will be fixed, and you will
be able to change the level continuously within a maximum range of ±10 dB by using only the electronic attenuator
designed for high-resolution setting.
(1) Setting the Level Continuous Mode
Press the [Shift] key and, then, the [∨] (Continuous) key in the Output Level zone. The characters "Cont" will
appear on the Output Level indicator, indicating that the continuous mode has been set up.
The output level setting range will be limited to ±10 dB with its center at the level that existed when the continuous
mode was activated, but you can vary the level within that range, free from momentary signal interruptions or
spike noise.
(2) Clearing the Level Continuous Mode
Press the [Shift] key and, then, the [^] (Normal) key in the Output Level zone. The characters "Cont" will go out
on the Output Level indicator, indicating that the continuous mode has been cleared.
