Chi tiết

datasheet

Power Range:
0.1 mW to 20 watts in five ranges, 40 Hz to 20 kHz; maximum rating is reduced by up to 50% (at 25 Hz), depending on impedance selected.

An auxiliary dB scale on the meter reads from -15 to +3 dB, referred to 1 mW.

Impedance Range:
0.6 Ω to 32 kΩ in two ranges; yielding 48 individual impedances spaced approximately 2 apart.

Accuracy
Impedance:
at 1 kHz, ±6% max, -0.5% avg;
70 Hz to 2.5 kHz, ±7% above 10 kW;
70 Hz to 5 kHz, ±7% below 10 kW;
at 20 Hz, -15% max, -8% avg;
at 20 kHz, ±50% max, ±12% avg
When impedance is specified, accuracy applies at full-scale on all ranges and impedances at 1 kHz;
when frequency ranges are specified, accuracy is at full-scale at ranges ≥20 mW at the specified impedances.
When a frequency limit is specified, accuracy is at full-scale at all impedances

Power:
at 1 kHz, ±0.3 dB;
50 Hz to 6 kHz, ±0.5 dB;
30 Hz to 10 kHz, ±1 dB;
at 20 Hz, -1.5 dB max, -1 dB avg;
at 20 kHz, -5 dB max, ±1.5 dB avg.

Waveform Error:
Meter will indicate true rms with as much as 20% second and third harmonics present in the input signal.

General
Cabinet:
Convertible bench cabinet, aluminum panel. Cabinet has extension legs to permit instrument to be used in a tilted position. Panel extensions,

Type 480-P212 Adaptor Plate Sets, are available for relay-rack mounting.

Dimensions: Panel - 12” W x 3.5” H (305 x 90 mm);

depth behind panel - 6.5” (170 mm)

Net Weight: 10.8 pounds (4.9 kg)
