 Leader 5835
The 5835 is a Stereo Audio Monitor that provides a lissajous pattern display of stereo audio signal on a CRT screen, enabling monitoring of the phase and level of the signal.
The lissajous pattern display of the stereo signal is provided with the left and right axes inclined at 45 degrees, enabling a good visual presentation of audio effects such as broadening and apparent position.
The 5835 features a stereo polarity discrimination function, a spot killer, and two Cannon-type inputs, making it ideal for use in not only program editing. but in checking of transmission equipment as well. All this makes the 5835 a useful stereo audio monitor for broadcast studio, production studio, and recording studio or remote pickup applications as well.
FEATURES
Parallel-connected male and female type XLR Cannon connectors are provided as standard for the balanced input configuration, enabling direct monitoring the lines required in broadcasting studio, production studio, recording studio, and remote pickup applications.
A stereo polarity discrimination function (patent pending) enables easy extraction and screen display of the audio signal during editing of commercial tapes, and when monitoring the output waveform from a broadcast stereo signal, thereby greatly simplifying the task of checking the phase of the stereo signal.
The 5835 is housed in an standard EIA half-rack size cabi-net, simplifying rack mounting and use in systems in combination with other equipment.
A 150 mm post-acceleration (12 kV) type CRT ensures a bright display.
The scale-illumination lamp can be replaced easily from the front panel.
A spot killer blanks the trace with no signal applied to prevent burn-in of the CRT phosphor. | | | |  Leader 5872A The 5872A is TV signal measurement monitor that integrate a waveform monitor with a vectorscope in one body. Waveforms and vectors can be independently or simultaneously displayed on a single CRT by operating the provided electronic switches (this feature is only available for horizontal time limit display).
Furthermore, a full-line selector function is installed for reading the field and line number on the CRT. As a result, These all models are very useful not only in observing the blanking time intervals for VITS, VIR, character broadcasting and ITS, but also in checking the various characteristics of video camera resolution.
FEATURES
150 mm rectangular CRT with internal graticule. The 16.5 kV high-accelerating potential facilitates legible, clearly defined display.
The full-line selector function used to select optional lines from the panel also monitor vertical interval test signals (VITS). Up to 9 fields and lines can be preset in memory.
The field and line numbers selected by the line selector function are displayed on the CRT for confirmation during waveform observation.
The dual-channel display function displays A and B inputs concurrently.
The newly developed power supply circuit enables instrument operation using supply voltages of 90 to 250 VAC without switching. The standard DC operation function (11 to 20 VDC) enables instrument use in vehicles.
All front-panel switches can be externally remote-controlled.
Differential gain (DG) / differential phase (DP) can be displayed through single mode key operations. | | | |  LV 5700A MULTI SDI MONITOR and LV 5710A HD SDI MONITOR The LV 5700A is a waveform monitor for HD-SDI and SD-SDI signals. The LV 5710A is a waveform monitor for HD-SDI signals. Both employ color TFT LCD screens. The functions of waveform monitors, vectorscopes, audio lissajous, and simple picture monitors are achieved with a single unit. Complete digital processing of SDI signals enables highly accurate measurements. In addition, extensive error detection functions and analysis functions are provided which allows the LV 5700A/LV 5710A to be used as SDI signal monitors.
Two serial digital input systems
The SDI input connector on the LV 5700A supports free rates. Thus, either HD-SDI or SD-SDI signals can be applied to the same connector. The LV 5710A only supports HD-SDI signals. You can select auto or manual setting for the input signal format.
Display
Employs an LCD monitor with XGA resolution. Various displays such as waveform display, vector display, picture display, and status display can be placed side by side on the XGA monitor. You can monitor these displays simultaneously. Depending on the combination, bowtie, embedded audio, and data dump can also be displayed. Furthermore, each display can be magnified.
Operation
The LV 5700A/LV 5710A can be controlled through the panel and remotely controlled through a computer via the Ethernet network. In addition, presets can be recalled using the remote connectors on the rear panel.
Extensive Analysis Functions
The LV 5700A can also be used as an analyzer to detect multiple types of transmission errors, detect gamut errors, display data dumps, analyze the contents of voice control packets, measure the equivalent cable length, and so on.
Output
Equipped with two active output connectors that reclock the input signal. One connector is an HD-SDI/SD-SDI switching type serial output; the other is a dedicated SD-SDI output. The dedicated SD-SDI output connector is not available on the LV 5710A. Other output connectors are the analog picture monitor output and the AES/EBU output that separates the embedded audio in the SDI signal. An analog XGA output connector is also provided allowing the screen to be displayed on an external monitor.
External Synchronization
Allows tri-level sync signals or B. B signals of NTSC and PAL to be input.
| | | |  | Leader LV 7700 The LV 7700 is capable of displaying the monitor waveform, image, and other data of HD-SDI and SD-SDI signals on an external display (SD-SDI signals only on the LV 7720). Display items include waveform monitor, vectorscope, audio monitor, simple picture display, as well as multi display on which these items can be arranged on a single screen. Its 1U half rack size reduces space consumption in broadcasting installations, etc. In addition, complete digital processing of SDI signals enables highly accurate measurements. It is also suitable as a monitoring device that monitors signals and detect errors via the network through the support of SNMP.
