5. CONTROL ELEMENTS

(See fold-out page)
1 Carry handle and setup bracket (adjustable).
The inclination of the generator can be adjusted by pulling the two holders apart and turning.
2 Display, 7-digit (LED)
3 System displays
mHz Milli-Hertz (exp. -3)
Hz Hertz (el. unit of frequency)
kHz Kilohertz (exp. 3)
MHz Megahertz (exp. 6)
G.T Display of the gate time (measuring impulse, G.T = Gate-Time)
4 BNC-socket for the frequency counter input (EXT COUNT IN)
The maximum input voltage is 250 Vpp.
5 BNC-input socket for the voltage-controlled frequency setting (VCF IN)
The maximum input voltage is 10 VDC!
6 BNC-socket for synchronous output (TTL-level)
7 BNC-socket for signal output (50 Ohm impedance)
8 ATT-switch for signal weakening (dampening -20 dB) at the output (7)
9 Setting controller for amplitude (signal voltage)
10 Switch for the output signal form (sine/triangle/rectangle)
11 Adjustment button with double function for the DC-offset
pushed: neutral DC-offset setting (middle position)
pulled: manual offset setting, movement of the signal progress upwards (+/positive) or downwards (-/negative)
12 Adjustment button with double function for the symmetry setting
pushed: Symmetry setting neutral
pulled: Manual symmetry adjustment possible, e.g. setting of pulse/pause ratio
13 Area selection buttons for the frequency control area (display x1 Hz to x1 MHz)
14 Adjustment button with double function for the wobble function
pushed: Wobble function off
pulled: Wobble function on with option of setting the bandwidth (Width)
15 Adjustment button for setting the wobble speed (Rate)
16 Fine adjustment controller for the generator frequency setting
17 LPF-button for low-pass frequency filter in the counter operation (for measurements in the NF range)
INT/EXT switching button for display (display of the internal generator frequency or the external counter
frequency)
18 Gross adjustment controller for the generator frequency setting
19 Mains switch for commissioning (ON / OFF)
20 Ventilator opening for device cooling
