Introduction

The MA243x0A series Microwave CW USB Power Sensors employ a single-path diode architecture to provide fast, accurate
average power measurements from 10 MHz up to 50 GHz with 90 dB of dynamic range.

Features and Benefits

• Broad Frequency Range (10 MHz up to 50 GHz): Ideal for general purpose, aerospace and defense, satellite and wireless

communications applications

• Accurate Power Measurements with over 90 dB Dynamic Range

• Best-in-Class Damage Protection (+26 dBm CW, +32 dBm peak < 10 µs): Protects instrumentation investment

• No Zeroing Required (for signals > –50 dBm) and Elimination of 1 mW Reference Calibration: Reduces test time and handling in

production while maintaining absolute accuracy

• Advanced Trigger Capabilities: Facilitates time dependent power measurements

• NIST Traceable Calibration: Provides high-accuracy measurements and ensures absolute accuracy

• Calibration Traceable to SI Units via National Metrology Institutes

• Easy to Use with PC or Select Anritsu Handheld Instruments: No benchtop power meter unit needed

• Silicone Protective Covering (removable): Provides additional field durability

• External Trigger Latching: For pulses as narrow as 20 ns

Set Drift

3. Power uncertainty expressed with coverage factor of k=2 for CW measurement after zero operation. Includes calibration factor and linearity over temperature uncertainties, but
not the effects of mismatch, zero set and drift, or noise.

4. Zero uncertainty expressed with coverage factor of k=3. One hour warm-up followed by a Zero operation. Measured with 256 averages and 40 ms aperture and with the
temperature kept within ±1 °C.
Zero Set: Average of the reported power over one hour.
Zero Drift: Two sigma value of the reported power over one hour.
Specified Zero Set, Drift and Noise are valid at 30 °C ± 5 °C.

5. Two sigma noise at 10.2 seconds of integration time (integration time = aperture time x averaging number). Effect of noise can be reduced by increasing the number of averages
and/or increasing the aperture time. Noise is inversely proportional to the square root of number of ADC samples used per measurement; the number of ADC samples per
measurement is the product of the sample rate, aperture time, and number of averages used. Noise uncertainty is expressed with coverage factor of k=3.

6. Offset correction feature is available only through the PowerXpert application. There is no remote command for it in the sensor firmware.

7. Maximum number of averages allowed in Continuous Average mode is 65,536. In Scope mode, the maximum number of averages is equal to 16,777,216 divided by the number of
data points.

8. Averaging resolution of 0.001 dB is not available with the PowerXpert application. It is defined as the place after the decimal to which the reading becomes stable.
For example, if 0.01 is selected, then the reading will typically be stable within ±0.01 dB. Please refer to the remote operation chapter in the user guide for information regarding
access to this feature.

9. Speed is defined as the data throughput at the “A” end of the USB A to Micro-B Cable (p/n 2000-2010-R), where:
Number of Repeat Averages = N (N = 1 for moving average mode)
Capture Time Coefficient = Ct = 8.238
Command Processing Time = T
Speed may vary depending on the speed of and load on the CPU controlling the sensor. Specified results obtained with Intel® Core™ i5-3550 CPU running at 3.30 GHz

10. Speed is defined as the data throughput at the “A” end of the USB A to Micro-B Cable (p/n 2000-2010-R), where:
