The Anritsu ML2419A is a power meter range calibrator engineered to verify measurement channels in Anritsu ML2400A Series Power Meters. It delivers a stable, accurate reference signal at 50 MHz and 0 dBm (1.000 mW) to ensure measurement reliability in metrology and calibration facilities. Remote control via the power meter enables fully automated calibration workflows.
## Technical Specifications
**Reference Signal Output**
• Nominal frequency: 50 MHz
• Reference power level: 0 dBm / 1.000 mW
• Output connector: Front panel 50 Ω precision N-type (female)
• Output accuracy: ±1.2 % per year
• Frequency accuracy: <1 %
**Signal Channel Ranges**
The ML2419A provides voltage testing across five overlapping ranges, spanning +7 dB to −70 dB relative to 1.0 V:
• Range 1: +7 dB to −12 dB (DC voltage)
• Range 2: −11 dB to −28 dB (DC voltage)
• Range 3: −25 dB to −44 dB (250 Hz chopped voltage)
• Range 4: −41 dB to −58 dB (250 Hz chopped voltage)
• Range 5: −56 dB to −70 dB (250 Hz chopped voltage)
Ranges 3, 4, and 5 employ 250 Hz voltage chopping to minimize offset and drift errors. The power meter applies a 309.5 gain factor in chopped-mode operation. Testing covers maximum and minimum power levels per range, except Range 5, which tests at maximum and 30 % of maximum. Adjacent ranges overlap, allowing single-voltage testing at boundary dB levels.
**Connectivity & Control**
• Sensor A connector: 12-pin circular precision connector for 1.5 m power sensor cables
• Remote operation via power meter menu system
**Power Supply**

• Height: 88 mm (3.46 in)
• Depth: 250 mm (9.84 in)
• Weight: 2.2 kg (4.84 lb)
## Key Features
• Five calibration ranges with overlapping coverage from +7 dB to −70 dB
• Dual operational modes: DC voltage (Ranges 1–2) and 250 Hz chopped voltage (Ranges 3–5)
• N-type RF output for direct sensor calibration reference
• Full remote control integration with ML2400A Series power meters
• Compact benchtop form factor
## Typical Applications
• Power meter range verification and calibration traceability
• Sensor signal channel testing across dynamic power ranges
• Automated calibration procedures in standards labs
• Periodic validation of RF power measurement systems
## Compatibility & Integration
The ML2419A integrates directly with Anritsu ML2400A Series Power Meters via the 12-pin sensor connector and can be controlled entirely through the power meter's menu interface, eliminating the need for separate control hardware.
