The Leader product range includes award-winning 3G/HD/SD SDI waveform monitors and rasterizer test instruments with customizable layout. Among available options are 4K/UHD, CIE colour chart, HDR measurement, test pattern generation, eye and jitter measurement and closed caption display, IP and 12G SDI. Leader has helped many customers manage their transition from analog to digital, from SD to HD, from HD to 4K/UHD, from SDR to HDR and from BT.709 to BT.2020 wide colour gamut. Leader also provides dependable support for the transition from SDI to IP.


The LV5300 is a waveform monitor with a 7-inch touch screen display in a compact 3 U enclosure operative with battery power supply.


The LV5350 waveform monitor offers a 7-inch HD screen display in a compact 3 x ½ RU package that can operate on AC or DC. Waveform, vector and picture with 4K 12G-SDI and audio options . Easy menu operation with touch screen, mouse, and front panel button controls.


The LV5600 is a hybrid-type waveform monitor compatible with 4K/HD/SD SDI signal and IP signal.


The LV7600 is a hybrid-type rasterizer compatible with 4K/HD/SD-SDI signal and HD/SD IP signal. The LV7600 is a rasterizer with the same function as the LV5600 in a 1U full rack enclosure.


LV7300 is a 1U half rack size rasterizer. It is compact but supports eye pattern measurement up to 12G-SDI.



The LT4670 is a 1U full rack size synchronous signal generator that outputs PTP, GNSS, (4K/HD) IP, 4K 12G, (3G/HD/SD) SDI, analog synchronous signals, AES/EBU, audio word clock and LTC synchronized to analog video sync signals.


The LT 4610 is 1RU full-rack size sync signal generator that can output triple-rate SDI (3G-SDI/HD-SDI/SD-SDI) signals. It employs two power supply units for redundant operation to protect against power supply failures. The genlock function for external sync signals enables SDI signals, six sets of analog black burst sync signals, and audio word-clock signals to be output synchronously. The genlock function is equipped with a STAY IN SYNC function that maintains the phase when errors occur in the input signal, making it possible to provide stable sync systems. In addition to test pattern output including color bars and SDI check fields, the LT 4610 can embed ID characters, QVGA logo marks, safety area markers, and embedded audio in a SDI signal output.


The LT4611 is a 1U full rack size sync generator that can operate in synchronization with GPS, BDS, PTP, CW, and internal reference signals, as well as Genlock that supports external analog video synchronization signals.

LT 4448

LThe LT 4448 is a changeover unit that automatically switches the signal from the primary signal to the backup signal when problems are detected in the primary signal.Two systems of input signals (primary and backup) are connected to the LT 4448, and the LT 4448 detects errors in the amplitude of the primary input signal. A single LT 4448 provides 11 pairs of BNC and LTC channels. These channels can receive SDI, NTSC/PAL black burst, HD tri-level sync, AES/EBU digital audio, word-clock, and LTC signals.

LT 4600A

The LT 4600A multi-format video generator is a compact, 1U half-rack size SDI video signal generator that supports the triple-rate SDI (3G-SDI/HD-SDI/SD-SDI) format. In addition to test pattern output including color bars and SDI check fields, the LT 4600A is equipped with numerous features such as ID characters, QVGA logo marks, safety area markers, audio embedding, genlock function for external reference input signals, and three analog black signal outputs.
