Up to 10 frequencies from 1mHz to 10MHz.
Manual from front panel MAN TRIG key.
50Ω and 600Ω (not independent).
2mV to 20V pk-pk open circuit, (1mV to 10V pk-pk into 50Ω/600Ω) in
four switch selectable ranges with 20dB vernier control within each
range. Amplitude can be displayed in V
0, -20dB, -40dB, or -60dB.
±0.2dB to 500kHz; ±2dB to 10MHz.
±10V. DC offset plus signal peak limited to ±10V from 50Ω/600Ω; CLIP
shows in display when offset plus signal peak exceeds ±10V. DC offset
plus waveform attenuated proportionally by the attenuator.
3 digits for both Amplitude and DC Offset.
A square wave at the main waveform frequency. Symmetry is 50% for
sine and triangle waves at MAIN OUT; for square waves symmetry is
the same as that of the waveform at MAIN OUT.
Outputs a trigger signal at the start of sweep to synchronize an
oscilloscope.
Output impedance 50Ω nominal. Logic levels of <0.8V & >3V.
