Description:
The TVM-675 is a full-featured half-rack width combination waveform monitor/vectorscope, audio monitor engineered to observe either composite or component analog signals. Stereo audio phase and levels may be monitored via the audio display. The audio may be displayed alone or in any combination with waveform and/or vector. One, two or three composite video signals may be observed individually or in any combination of three inputs. Waveforms can be displayed in ether parade modes or overlayed for comparison of timing and amplitude characteristics. All three composite inputs may be displayed simultaneously with Flat, Low Pass and Chroma filters. Vector displays can also be overlayed for simultaneous observation and comparison of the phase and amplitude of up to three composite signals. The TVM-675 can display component analog video signals from Y/C, Beta, SMPTE, EBU or M-II® standards of 75% and 100% equivalent saturations. Component vectors may be displayed by themselves or in combination with the waveform display. Four user-defined memories permit rapid recall of frequently used modes. Diagnostic testing of the front panel controls and LEDs is built in. An R-Y (V-axis PAL) mode displays the demodulated chrominance with horizontal sweep. A graticule scale is provided to aid in measuring differential phase. This display may be viewed simultaneously in the parade mode with one or two additional filter waveforms. The TVM-675 is ideal for multi-format analog video and stereo audio monitoring. |
Features:
• INPUTS: Three composite loop through or one CAV loop through. In the composite mode any input can be selected as reference. In the CAV mode only “A” or “Ext Ref” can be selected as reference.
• DISPLAYS: Waveform parade or overlay of three composite inputs and three filters. Composite vector overlay of three inputs. Combination of vectors overlayed and waveforms paraded and/or overlayed simultaneously. Up to twelve different composite functions/filters can be displayed simultaneously. CAV waveforms, paraded or overlayed, and/or vector displayed individually or in combination.
• STEREO AUDIO: Calibrated X-Y input Lissajous display of either balanced or unbalanced audio. Shows phase and signal level of the audio signal. Input level is selectable for 0, +4, +8 or +12dBm.
• MEMORY: Storage and recall of four user defined front panel setups.
• FREQUENCY RESPONSE: Flat to 10 MHz ±1%.
• GRATICULE: Internally etched to eliminate parallax errors.
• HIGH BRIGHTNESS CRT: With non-glare contrast filter for enhanced visibility.
• FILTERS: Flat, Low Pass, Chroma.
• R-Y MODE: Improved resolution of differential phase measurements of composite inputs. (V-axis PAL).
• DC RESTORATION: Maintains display baseline stability with varying APL. |
