Anritsu ML2419A – Power Meter Range Calibrator

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
