1-5 Verification and Test Chapter 1 — General Information

1-5 Verification and Test

The ML2419A Range Calibrator provides a traceable series of voltages to facilitate accuracy measurements for the ML2430A and ML248xx / ML249xA Series Power Meter signal channels. The voltages are produced by means of a precision voltage reference and a series of switchable attenuators, operated by a microcontroller. All voltages produced are accurate, stable, and low-noise such that errors inherent in the Range Calibrator itself do not contribute significantly to the error measurements of the signal channel.

Instrument Control

The Range Calibrator is controlled remotely using the ML24xxx Series Power Meter menu system via the sensor cables. On connection of a sensor cable, the meter automatically senses the presence of the Range Calibrator. From this point, the Range Calibrator is controlled using the ML24xxx keypad and displayed menus.

Test Conditions

The Range Calibrator is intended for use as a calibration instrument, and as such must be operated under controlled conditions of temperature and humidity in order to meet its specified precision and stability.

All tests must be performed at 25 °C ± 10 °C (77 °F ± 18 °F) and a relative humidity of less than 75 % at 40 °C (104 °F), non-condensing.

Prior to making any precision measurements, allow the Range Calibrator and the Power Meter to warm up for a period of 15 minutes from power on. If the power supply is interrupted for any reason, allow a similar settling period.

4-1 Performing a Verification

The performance of the Anritsu ML2430A Series Power Meter’s individual signal channel inputs are verified using the following procedure. References in this procedure to sensor input B apply to model ML2438A (dual-channel) power meter only. Before starting this procedure, refer to Section 1-5 “Verification and Test” for information on the appropriate Test Conditions.

1. Connect the Range Calibrator to the Power Meter using 1.5 meter sensor cables. The inputs to be verified must be connected to the corresponding connectors on the Range Calibrator; that is, connect Power Meter connector A to Range Calibrator connector A, and connector B to connector B (ML2438A only).

2. On connection of the sensor cables, the meter automatically detects that a Range Calibrator is present and displays the performance verification menus.

Figure 4-1. ML2419A Range Calibrator Top Menu (single-channel power meter)

Figure 4-2. ML2419A Range Calibrator Top Menu (dual-channel power meter)

3. The performance verification tests will begin when the soft key for the sensor input to be verified is selected. For single-channel power meters (ML2437A), press the A soft key. For dual-channel models (ML2438A), press A, B, or A and B. If the “A and B” soft key is selected, all measurements are first taken on sensor input A, then repeated for sensor input B. Performance verification tests for each sensor input are performed in the following sequence:

• The signal channel input is zeroed.

• The Power Meter signal channels are checked at the upper and lower levels of each measurement

range. A null is performed at each range setting prior to every measurement.

4-2 RF Calibrator Chapter 4 — Operation with an ML2430A Series Power Meter

4-2 RF Calibrator

The Range Calibrator RF Calibrator output can be used to approximate the 0.0 dBm at 50 MHz reference calibration of a sensor. Calibration is accomplished using the ML2430A Series Power Meter Cal/Zero menu. Sensors should be zeroed before being calibrated (refer to the ML2430A Series Power Meter Operation Manual, part number 10585-00001). Zeroing a power sensor compensates for noise and thermal EMF of the device under test, and is recommended prior to taking important power readings in the bottom 20 dB of a power sensor’s dynamic range.

When the sensor is first attached, the message SENSOR x ZERO not done (where x = A or B as appropriate) is displayed. Perform the sensor zeroing procedure described in the ML2430A Series Power Meter Operation Manual.

After zeroing the power sensor, perform the following procedure to calibrate the sensor:

1. Connect the sensor to the ML2419A Range Calibrator 50 MHz, 0.0 dBm reference output connector labeled CALIBRATOR.

2. Press the Cal/Zero front panel key and the Cal 0 dBm soft key, then select the appropriate sensor. Note that if only one sensor is connected, the A and B selection is not displayed and the calibration process begins immediately.

3. On successful completion of the calibration operation, the buzzer sounds.

The sensors can also be calibrated using the GPIB CAL command (refer to the programming section of the ML2430A Series Power Meter Operation Manual).

4-3 Interpreting the Results

The tabular data presented consist of the values read by the meter for each range, with one measurement taken at each end of each range. For each of these measurements, there is an expected value. These measured values must meet the specification limits defined in Appendix A, “ML2419A Range Calibrator Specifications”.

dB Error Figure

The Range Calibrator measures the “Zero” level, and the “Upper” and “Lower” limits of each of the five ranges (both channels on a dual-channel meter). To calculate the dB Error Figure for each level, subtract the expected level from the measured level.
