Match the output impedance between the F/G output and the unit under test by switching the impedance output
select switch (27).

In case that you want to measure the frequency under process, please refer to the section 5.1.4 for further
information.
5.2.3 Wave
Forms
The basic ramp signal has been generated by the OP Amp. Based on this basic signal, the squarewave has been
formed by the line receiver IC. And, the sinewave has been formed by the quardruple TR IC.
The output wave forms and phase relationship are as follows.
Note:
Under activation of the 600
Ω
impedance mode (27), the output wave forms can be normal up to 100 kHz
range.

Note:
The output frequency can be read by multiflying figures optioned by the frequency control dial (24), and the frequency
Range select switch (26).
Ex. 1 kHz = 0.1 (at the dial 24) x 1 K (at the S/W 26)
