Product Description

TECHNICAL PARAMETER 1). Output frequency Frequency range: 0.2Hz~2MHz seven ranges:0.2Hz-2Hz, 2Hz-20Hz, 20Hz-200Hz, 200Hz-2kHz, 2kHz-20kHz, 20kHz-200kHz, 200kHz-2MHz, Output signal impedance: 50Ω Output signal wave-form: sine wave, square wave, rectangle wave, sawtooth wave and triangle wave Output signal amplitude (peak-peak value): non-attenuate (2Vp-p~20Vp-p)±20% continuously adjustable attenuate 20dB (0.2Vp-p~2.0Vp-p)±20% continuously adjustable attenuate 40dB (20mVp-p~200mVp-p)±20% continuously adjustable The above are measured with load 1MΩ, the output signal amplitude will be half of standard at 50Ω load. Function output symmetry adjust scope: 20%~80% (±10%) 6). Output signal features: sine wave distortion:<2%, triangle wave linear:>99% (10%-90% of output amplitude), square wave rise edge times: less than 100nS (10%-90% of output amplitude), square wave fall edge times: less than 100nS (10%-90% of output amplitude), square wave rise and fall pulse less than or equal to 5%Vo (50Ωload). Test condition: frequency output: 10KHz, amplitude: 5Vp-p,warm-up for 20minutes. Output signal frequency stability: less than ±0.1%/min (test condition is the same as the above) Amplitude display (only for 50Ω load, at 1MΩ load, the real output amplitude is double of the displaying value): Display digits:2/3 digits (decimal point automatic select place). Display units: Vp-p or mVp-p. Display errors: Vo±10%±1d (Vo refers to the true value of output signal) Resolution: non-attenuate 0.2Vp-p 20dB attenuate:20mVp-p 40dB attenuate:2mVp-p Frequency display: display range: 0.2Hz-2MHz display effective digit: four or five digits. Measurement errors: ≤0.5% Time base: frequency: 12MHz frequency stability:±5x10-5 Working temperature: 0℃~40℃ Size: 270mm x 215mm x 100mm Power applicability and consume: 110V/220V±10% 50Hz/60Hz±5%, power consume ≤15W

Verified Purchase
Comes in a nice plastic case.
Does not show output voltage unless driving a 50 ohm load. Otherwise the voltage is approximately 2x the displayed value.
It does not remember it's last setting so you must select the wave form mode, frequency range and set the frequency each time you turn it on. I does not have a DC offset or any way to adjust offset so wave forms are references +/- ground.

1 of 1 people found the following review helpful By Joe Thomas on October 11, 2014
The biggest problem with this unit is its signal voltage offset, which occurs with all of its waveforms. The offset is more or less proportional with amplitude, and there is no way to adjust it away! Somewhat surprising, since these waveforms are digitally derived.

Additionally, the quality of the instructions are quite poor. Being as brief as they are, it would have been a good idea to run the text past a native english speaking engineer from the US or a commonwealth nation to correct spelling, punctuation, and sentence form.
