The popular single channel VDA110M HD gives a maximum of eleven outputs or ten outputs with a loop-through and has board edge control. The VDA110R HD is a remotely-controlled single channel board which gives a maximum of eleven outputs or ten outputs with a loop-through.

For reduced cost multi-channel applications where fewer outputs are required, the dual channel manually-controlled VDA210M HD is perfect, giving a maximum of five outputs per channel (or four outputs with a loop-through). The VDA210M HD also has the flexibility to be configured as a single channel board for those applications where more outputs are required. 

Technical Details

Standard Crystal Vision modules 266mm x 100mm

Weight: 140g (VDA110M HD and VDA110R HD); 160g (VDA210M HD) Power consumption: 1.4 Watts (VDA110M HD and VDA210M HD); 4 Watts (VDA110R HD)

ANALOGUE VIDEO INPUTS

VDA110M HD and VDA110R HD: One SD or HD analogue input VDA210M HD: Two SD or HD analogue inputs

SD composite video input, 1 volt with syncs. Composite PAL or NTSC. Component video up to 30MHz bandwidth

SD Black and Burst or HD tri-level syncs reference 

VDA110M HD and VDA110R HD: Loop-through available with RM16 frame rear module, or 75 ohm termination

VDA210M HD: One loop-through per channel available with RM15 rear module, or 75 ohm termination Loop-through does not need VDA to be fitted – rear connector has all circuitry required

VDA110M HD and VDA110R HD:

 Differential input with RM02 and

 RM16 rear modules

VDA210M HD: Differential input with RM02 (first channel only) and RM15 rear modules

ANALOGUE VIDEO OUTPUTS

 VDA110M HD and VDA110R HD: Maximum of eleven outputs using the RM18 rear module (five outputs with RM01, eight with RM02 and ten with RM16)

VDA210M HD: Maximum of five outputs per channel using the RM18 rear module (four outputs per channel with RM15, three of the first channel and four of the second with RM02, and two per channel with RM01)

PERFORMANCE

Input Return Loss: >48dB to 10MHz

Output Return Loss: >48dB to 10MHz

Frequency Response: +/-0.05dB

0 to 6MHz, +/-0.2dB 6 to 10MHz, +/-1.5dB 10 to 30MHz Differential Gain: <0.2% at 5MHz (VDA110M HD and VDA210M HD); <0.3% at 5MHz (VDA110R HD) Differential Phase: <0.4 degrees at 5MHz (VDA110M HD and VDA210M HD); <0.6 degrees at 5MHz (VDA110R HD)

Signal to Noise Ratio at 0 to 10MHz: <70dB (VDA110M HD and VDA210M HD); <60dB (VDA110R HD)

Cable equalisation: Belden 8281 manual adjustment up to 300m (can also be adjusted remotely on VDA110R HD)



 Gain adjustment: +/-3dB manual adjustment (can also be adjusted remotely on VDA110R HD)

On the VDA110R HD the output clamping can be set to suit the type of material being transported. These are fast clamp (six lines recovery time), slow clamp (60 lines recovery time) and off (AC-coupled)
