20W 40W 60W 100W Audio signal Sweep Frequency Generator 20W Low Frequency signal Generator Sweep Frequency Instrument LW-1212BL

Audio Signal Sweep Frequency Generator 20W Low Frequency Signal Generator Sweep Frequency Instrument LW-1212BL

📋Specification

Feature:

With the novel RC oscillation technology, the sine wave distortion is small, which is especially suitable for hearing the pure tone of loudspeakers.
Digital display is adopted for frequency display and output amplitude, with more accurate reading and less error.
Sweeping start point and end point can be adjusted at will.
High output power, up to 150W.
Sine wave output amplitude:
- 1212BL: 0-12.8rms 8 Ω load
- 1212DL: 0-18rms 8 Ω load
- 1212E: 0-22rms 8 Ω load
- 1212F: 0-28.5rms 8 Ω load
Indication error of output voltmeter: ± 10% (full scale)
Output voltage display error: ± 10% ± 2 words (when the output amplitude value is greater than 1/10 of the maximum output amplitude, only for LW1212BL/DL)
Sine wave frequency response: ± 0.4Db (based on 1 KHz, manual working state)
Sine wave distortion, no more than 0.5% 100Hz -- 20KHz, other frequencies no more than 0.8% (20W, 8 Ω load)
Output power:
- LW1212BL: 20W frequency is not more than 20 KHz, 8 Ω load 12.8rms
- LW1212DL: 40W 8 Ω load
- LW1212E: 60W 8 Ω load
- LW1212F: 100W 8 Ω load
Sweep mode: logarithmic
Sweep frequency ratio: no less than 1:1000
Synchronous output: TTL square wave (except LW1212D/DL/E/F)
Voltage control input (VCF) voltage range: 2V ~ -1V deviation ± 20% (LW1212D/E/F/DL only)
Working power supply: 220V ± 10% 50HZ ± 2HZ
Working environment: temperature: 0 ℃ - 40 ℃ | Humidity: no more than RH90% | Atmospheric pressure: 86KPA ~ 104KPA
Boundary dimension: 1212BL/DL/E/F 320MM * 360MM * 100MM
Weight:
- 1212BL: 8KG
- 1212DL: 10KG
- 1212E: 12KG
- 1212F: 15KG
