The conformity test made by HAMEG is based on the actual generic- and product standards. In cases where different limit values are applicable, HAMEG applies the severer standard. For emission the limits for residential, commercial and light industry are applied. Regarding the immunity (susceptibility) the limits for industrial environment have been used. The measuring- and data lines of the instrument have much infl uence on emmission and immunity and therefore on meeting the acceptance limits. For different applications the lines and/or cables used may be different. For measurement operation the following hints and conditions regarding emission and immunity should be observed: 1. Data cables For the connection between instruments resp. their interfaces and external devices, (computer, printer etc.) suffi ciently screened cables must be used. Without a special instruction in the manual for a reduced cable length, the maximum cable length of a dataline must be less than 3 meters and not be used outside buildings. If an interface has several connectors only one connector must have a connection to a cable. Basically interconnections must have a double screening. For IEEE-bus purposes the double screened cables HZ72S and HZ72L from HAMEG are suitable. 2. Signal cables Basically test leads for signal interconnection between test point and instrument should be as short as possible. Without instruction in the manual for a shorter length, signal lines must be less than 3 meters and not be used outside buildings. Signal lines must screened (coaxial cable - RG58/U). A proper ground connection is required. In combination with signal generators double screened cables (RG223/U, RG214/U) must be used. 3. Infl uence on measuring instruments. Under the presence of strong high frequency electric or magnetic fi elds, even with careful setup of the measuring equipment an infl uence of such signals is unavoidable. This will not cause damage or put the instrument out of operation. Small deviations of the measuring value (reading) exceeding the instruments specifi cations may result from such conditions in individual cases.

Settings are changed with or . FREQUENCY (adjustment knob) Continuous and linear frequency fi ne ad-justment, with the setting range from 0.09 to 1.1 (approx 0.045 to 1.1 in 10 MHz- range) overlapping the ranges selected with FREQUENCY (2 pushbuttons) Frequency range selection from 50 mHz to 10 MHz in 8 de- cade steps.

TRIGGER OUTPUT (BNC connector) This short-circuit-proof output supplies a square signal in synchronism with the output signal. It is TTL compatible and has a duty-factor of approx. 50%. OFFSET (adjustment knob) Adjustment of the positive or negative offset voltage. This DC voltage can be super-imposed on the output signal. The max. offset voltage is 5V (o.c.) or 2.5V respectively when terminated into 50. The offset voltage is available to all functions except for pulse and activated by . In operation mode OFF (no function activated) it can be used separatey. In pulse mode the pulse width is set with this control from 10% to 90%. ON (pushbutton) Activates the offset function except in pulse mode. If the ON-button is pushed in pulse mode, pulse width is set with the control from 10% to 90%. In OFF-position the fi xed pulse width amounts to 50%. 50 OUTPUT (BNC connector) Short-circuit proof signal output of the generator. The output impedance is 50 and the max. output amplitude is 20 Vpp (o.c.) or 10 Vpp respectively when terminated into 50. 20dB, 20bB (pushbutton) Two fi xed attenuators, 20dB each. They can be used se- parately. When both pushbuttons are activated, a total at- tenuation of 40dB results. Including the amplitude control , the max. attenuation amounts to 60dB (factor 1000). AMPLITUDE (adjustment knob) Continuous adjustment of the output ampli-tude from 0 to 20dB terminated into 50. 7 Subject to change without notice Adjustment Adjustment Please observe the correct sequence of steps!
