憑借其采集速率達(dá)100平均譜圖/秒的能力，F(xiàn)ASTFLIGHT-2成為L(zhǎng)C/TOF-MS/和GC/TOF-MS應(yīng)用中優(yōu)異的數(shù)據(jù)采集解決方案。色譜技術(shù)正在向更短的保留時(shí)間發(fā)展，使得飛行時(shí)間質(zhì)譜（TOF-MS）獲取平均譜圖的速度越來越快。對(duì)比代的數(shù)字信號(hào)平均器，F(xiàn)ASTFLIGHT-2 將TOF譜圖處理速度提高了10倍，因而有能力適應(yīng)更快的色譜儀。
由于使用了采樣ADC以及硬件數(shù)字信號(hào)平均器，F(xiàn)ASTFLIGHT-2能處理LC/TOF-MS, GC/TOF-MS, Ion-Trap/TOF-MS 和 MALDI I TOF-MS中碰到的高速離子而不用像在時(shí)間數(shù)字轉(zhuǎn)換器（TDC）中遭受死區(qū)時(shí)間的困擾。對(duì)比瞬時(shí)數(shù)字轉(zhuǎn)換器以及數(shù)字采樣示波器，他們都面臨緩慢的軟件平均速度，F(xiàn)ASTFLIGHT-2傳遞平均譜圖的速度比它們快了好多個(gè)數(shù)量級(jí)。
其創(chuàng)新的，自動(dòng)關(guān)聯(lián)噪聲消減特性意味著FASTFLIGHT-2在QqTOF-MS低速離子應(yīng)用中也是有效的解決方案，這一領(lǐng)域以前一直被認(rèn)為都是TDC和時(shí)間轉(zhuǎn)換器所。

| Amplitude Digitizing Resolution | 8 bit- ADC nominally spans 500 mV at the Analog Input. |
| Precision Enhancer | Extends the limiting ADC resolution to 12 bits (for input noise <2 mV) when circa 256 or more records are averaged3. Optionally, on or off. |
| Differential and Integral Non-Linearity (DNL and INL) | Measured from 5% to 95% of full scale using a 500 mV, 70 µs ramp, with Precision Enhancer on. DNL within ±0.1 LDB referred to the 8-bit ADC. INL within ±0.4% of full scale. |
| Analog input Bandwidth | DC to 500 MHz; rise adn fall times <1 ns. |
| Equivalent input Noise | (Measured with 500 ps sampling and 50 µs record lenght.) Uncorrelated with the Trigger <2 mV rms. Correlated with the Trigger <0.02 mV (typically 0.01 mV rms) with Automatic Correlated Noise Substruction. |
| Automatic Correlated Noise Substruction | Automatically assesses the correlated noise in each spectrum and substracts it without compromising data throughout rates. Optionally, on or off. |
| Analog DC Offset (Vertical Offset) | Zero offset of the ADC is computer adjustable from -250 mV to +250 mv with 0.03 mV resolution, referred to the Analog input. |
| Sampling intervals | Hardware 500 ps, 1 ns or 2 ns real-time sampling with one scan per pound; 250 ps interleaved sampling with two scans per second4. Software can display 250 ps interpolated sampling from a spectrum sampled at 500 ps. |
| Record Size (Hardware) | 8 bits per sampled point and up to 1.5 M points per record (at 250, 500, 1000 ir 2000 ps/point. Record length selectabel from a minumum of 10 µs to a maximum of 1.5 M points in steps of 512 points. |
| Spectrum Size (Hardware) | Identical to Record Size, except 24 bits per sampled point, providing rapid hardware summing of up to 65,535 records ub a spectrum. |
