Minhe OCXO Frequency Standard 10MHz Distribution-Amplifier, 8 Channel BNC/Q9 Output, for High-Precision Signal Distribution in Laboratory and Measurement Systems(Built-in OCXO)

Features:* High-stability reference architecture: Utilizes an oven-controlled for crystal oscillator (OCXO) core using SC-cut for crystal technology, achieving frequency stability ≤±50ppb and phase noise of -172dBc/Hz @ 100kHz. Built-in G-sensitivity compensation circuitry (0.3ppb/g vibration tolerance) ensures 10MHz reference signal integrity even in vibrating environments.* Intelligent signal distribution system: 8-channel BNC/Q9 output interface (10dBm/1Vrms per channel), supports dynamic impedance matching (50Ω/75Ω adaptive), harmonic suppression >40dB, spurious suppression >70dB, and inter-channel isolation ≥60dB, capable of driving multiple test instruments simultaneously.* Dual-mode input redundancy: Simultaneously receives both the internal OCXO and an external 10MHz reference signal (0.1-5Vpp input range), automatically switching priorities and achieving ±2ppb voltage/load stability. If an external signal anomaly is detected, the internal oscillator is switched within 50ms. * Power Management: Wide-band DC 11.7-12.9V input (peak withstand voltage 15V), featuring a three-stage filtering + surge for protection design, maximum power consumption 12W, and guaranteed output amplitude fluctuation ≤±0.5dB in an ambient temperature range of -30°C to +70°C.* Modular Expansion Interface: Reserved expansion slot for GPSDO taming, supports pulse input synchronization (optional), is compatible with the IEEE 1344 time protocol, and allows real-time monitoring of for crystal oscillator aging rate (±0.5ppb/30 days) and temperature compensation status via the I²C interface.Specifications:Part Name: 10MHz Distribution AmpType: Built-in OCXO, without OCXO (optional)Material: PCB, metalColor: As shownDimensions: Approx. 63*43mmPower Supply: DC 11.7-12.9V, Maximum 12WInput: 10M, 0.1Vpp-5VppOutput: 8 ports, 1Vrms (13dBm)LED: Power IndicatorEXT 10M: External 10M InputERROR: No Output (Internal OCXO Fault)Accessories: AC110-220V - DC12V / 1.5ASize: W*H*L = 100*55*120 (including BNC connector)Weight: Approx. 600g (net)Package Contents:1 x 10MHz Distribution Amp
