TTL modulation signal, the frequency of 0 ~ 10KHz

[onsatmex5]

I am looking at a projector on line, one of the specs read like this>>

"TTL modulation signal, the frequency of 0 ~ 10KHz (may be do analog modulation)"

Can someone explain what this means...I am a novice and i'm in the process of trying to understand what some of the terminology means

I know TTL means you can only be "on or off" and analog means you can dim the output....

Here is the whole description of what I was reading >>
Laser power : 1000mW/R640, 1000mW/G532, 1000mW/B450 laser color : red, green, yellow, cyan, blue, purple, white power rating : 130W Laser Modulation : TTL modulation signal, the frequency of 0 ~ 10KHz (may be do analog modulation) Scanning System : High-speed closed-loop galvanometer scanning> 25Kpps (40Kpps optional); optical angle ± 20 degrees Control mode : 4 sets of built-in programs (two sets of automatic voice +), test procedures, DMX control (2 kinds of mode selection, 13 channels), master and slave functions, SD card and ILDA standard interface (with ILDA signal conversion function intelligent control functions : built-in 128 animated graphics, a variety of wave-changing effect; dual pattern independent control technology; with The initial system parameters auto-correction feature; no audio input laser "black market" feature HMI : push-button LED digital display control interface; patterns mirror set; original key digital voice regulation. optical performance : professional-level optical system dust technology, long-term use without the need for regular cleaning of optical system security : the key switch; remote emergency safety switch; rings installed to protect the double demonstration effect : pattern with a broken pen, rotate, zoom, flip, move, gradually drawing, Strobe , three-dimensional animation and other effects, can change the pattern according to customer requirements, flexible writing. do text, animation, advertising and other laser beam show and power : AC100V-240V, 50/60Hz work environment : 10 ~ 40 ° C indoor application site : with in DISCO, HIGH bar, entertainment bar, nightclub, television, opera, advertising and other places to use higher
