1007 / 1014 / 1016 output impedance is 50Ω, if the load is greater
enough than 50Ω, it will result in the load voltage drop equal to the open circuit of the
function generator output, approximately. If the load is 50Ω, the load voltage drop is
equal to one half of the open circuit of the function generator output voltage.
c. For Small Signal Output :
• For small signal output, it is suggested to add the attenuator, for example: -20 dB, to the
function generator output, and adjust the desired output level. This is the method for
getting the best signal / noise ratio.
d. For Large Signal Output :
•
In general, the function generator output is 20Vp-p in open circuit, and the output current
is limited to less than 100mA. For high voltage and high current output in special
applications, the external power amplifier is needed.
