Specification
(All specifications apply after warm-up in an ambient temperature range 18oC-28oC.)
OPERATING RANGE
Frequency Range: .005Hz to 5MHz in 7 overlapping decade ranges with fine
adjustmentby calibrated vernier.
Internal Mode
Vernier Range: 1000:1 within each range.
Vernier Accuracy: Better than ±5% of full scale.
External (Sweep) Mode :
Sweep Range: 1000:1 within each range.
FUNCTIONS
(Specifications apply for vernier between 0.5 and 5.0 and output 10V peak-to-peak into 50Ohm
termination).
Sine
Distortion: Less than 0.5% to 50kHz, less than 1% to 500kHz; all harmonics
>30dB below fundamental on 1M range.
Amplitude Flatness: ± 0.2dB to 500kHz; ±1dB to 5MHz.
Triangle
Linearity: Better than 99% to 500kHz.
Squarewave
Rise and Fall Times: <45ns.
Mark: Space Ratio: 1:1 ±1% to 100kHz; ± 5% to 5MHz
DC
Range: ±10V from 50 Ohm.
OPERATING MODES
Run
Generator runs continuously at the selected frequency.
Triggered
Generator is quiescent until triggered by an external input at TRIG IN or by pressing MANUAL. One
complete cycle is then generated at the selected frequency, starting and stopping at the phase set
by the START/STOP PHASE control.
Gated
Generator is quiescent until gated by an external signal at TRIG IN or by pressing MANUAL.
Generator then runs continuously at the selected frequency for duration of gate signal, starting and
stopping at the phase set by the START/STOP PHASE control. Last waveform started is
completed.
Manual
Manually operates generator as described in Triggered and Gated sections.
Start/Stop Phase
The START/STOP PHASE control varies the triggered and gated signal start/ stop point from
approximately -90o to +90o up to 500kHz.
