Turn mains switch [20] on unswitched position O.
Connect the device to the mains.
It is useful to remember that the device body remains connected to the safety earth
terminal as well as to every connector of the equipment.
4.3 Operating instructions
In order to check the appliance previously or to become familiar with controls, we
recommend to keep them in following positions (for subsequent uses, control position is
different).
[1] Range selector
[2] Frequency control
[4] Signal selector
[5] Variable symmetry selector
[6] Variable symmetry control
[7] Modulation selector
[8] Modulation and sweep controls
[9] Trigger control (TRIGGER)
[10] Amplitude control
[11] Output attenuator
[12] Direct voltage level control DC OFFSET
[13] Polarity selector
[15] Frequency range selector
[16] Frequency control
[17] Function and sweep selectors
[18] Symmetry control
[24] Internal / External trigger selector
[25] Single / Multiple trigger selector
Turn mains switch to I position (connected). Indicator [3] will light on and the device
is running.
With controls set on previously mentioned positions, a square signal will be supplied
on the 1 to 10 kHz range by the generator, without modulation, through connector [14].
Output voltage will be 2 to 20 Vpp in open circuit, depending on position set by control [10].
Next section describes the different operating modes.
