Description
The E4412A and E4413A power sensors are diode power sensors. They are intended for measurement of CW microwave power levels in a wide dynamic range from 70 dBm to +20 dBm (100 pW to 100 mW). The E4412A measures at frequencies from 10 MHz to 18.0 GHz. The E4413A measures at frequencies from 50 MHz to 26.5 GHz. These are high-speed power sensors, and do not incorporate narrow-bandwidth averaging used in average-power sensors. Signals with digital, pulse, or other forms of ampli tude modulation may introduce measurement errors. Multi-tone signals (containing multiple frequency components), or signals with significant har­monic content (> 45 dBc) may introduce measurement errors at high power levels. (Specifications for the power sensors are in Table 1.)

Figure 2 Relative Mode Power Measurement Linearity
with Power Meter/Sensor at 25° C (Typical)
The chart in Figure 2 shows the typical uncertainty in making a relative power measurement with the E44XX-Series power meter in the Rel (rela­tive) mode. In a relative measurement, two power levels are compared using a single sensor. The typical measurement uncertainty can be found by draw­ing a vertical line at the power level used as a reference, and a horizontal line at the power being measured. The region where these two lines intersect shows the typical uncertainty. This assumes that the reference power and the measured power are at the same frequency, and neglects errors due to zero set, zero drift, and noise. It also assumes no change in mismatch when mea

suring the “Power level used as reference” and the “Power level being mea­sured.” This chart illustrates that the best relative power measurement accuracy is obtained when the reference and the measured power levels are equal to, or less than, 20 dBm. Care in choosing the power levels can yield improved measurement accuracy. Example A illustrates a relative gain (amplifier measurement) and example B illustrates a relative loss (insertion loss measurement).
EXAMPLE A (Amplifier Gain Measurement):
Input power (reference) = 35 dBm; power measured = +6 dBm, so the rela­tive gain is +41 dB. The chart indicates a typical error of ±6%, which corre­sponds to +0.25 dB/ 0.27 dB uncertainty in the gain measurement.
EXAMPLE B (Insertion Loss Measurement):
Reference power = 25 dBm; power measured = 35 dBm, for the case of an insertion loss of 10 dB. The chart indicates a typical error of ±1%, which corresponds to
± 0.04 dB uncertainty in the measurement.
Calibration Factor (CF) and Reflection Coefficient (Rho)
Calibration factor and reflection coefficient data are given at 1 GHz incre­ments on a data sheet included with the power sensor. This data is unique to each sensor. If you have more than one sensor, match the serial number on the data sheet with the serial number on the power sensor you are using. The CF corrects for the frequency response of the sensor. The power meter auto matically reads the CF data stored in the sensor and uses it to make the cor­rections.
Reflection Coefficient (Rho, or ρ) relates to SWR according to the following formula:
SWR = (1+ρ)/(1-ρ)
Maximum uncertainties of the CF data are listed in Table 2 for the E4412A power sensor, and in Table 3 for the E4413A power sensor. The uncertainty analysis for the calibration of the sensors was done in accordance with the ISO/TAG4 Guide. The uncertainty data reported on the calibration certifi­cate is the expanded uncertainty with 95% confidence level and a coverage factor of 2.

Operation and Service Guide

Service

Service
Service instructions consist of principles of operation, troubleshooting, and repairs.
Principles of Operation
The A1 Bulkhead assembly provides a 50 ohm load to the RF signal applied to the power sensor. A diode assembly in the bulkhead rectifies the applied RF to produce a dc voltage which varies with the RF power across the 50 ohm load. Thus the voltage varies with the RF power dissipated in the load. With maximum specified RF power (100 mW) the dc voltage is approxi­mately 1V.
The low-level dc voltage from the bulkhead assembly must be amplified before it can be transferred on standard cables to the power meter. The amplification is provided by an input amplifier assembly which consists of a chopper (sampling gate) and an input amplifier. The chopper circuit converts the dc voltage to an ac voltage. To do this, the chopper uses two field effect transistors (FETs), A2Q1 and A2Q2, controlled by a 440 Hz square wave generated by the power meter. The amplitude of the sampling gate output (drain of A2Q1, source of A2Q2) is a 440 Hz square wave which varies with the RF power input. The 440 Hz ac output is applied to the input amplifier A2Q3 which provides the input to the first amplifier stage in the power meter.
The E44XX-Series power meter automatically detects when an E44XX­Series power sensor is connected and downloads the correction data from the sensor’s EEPROM. This configures the power meter to operate over the +20 dBm to 70 dBm power range with that particular sensor’s unique correction data applied.
Troubleshooting
Troubleshooting information is intended to first isolate the power sensor, the cable, or the power meter as the defective component. When the power sen sor is isolated, a “Restored Sensor Module” must be used for repair. See Table 6.
24
-
Operation and Service Guide
Service
If error message 241 or 310 is indicated on the power meter, suspect a failed power sensor. If no error message is displayed, but a problem occurs when making a measurement, try replacing the cable from the power meter to the power sensor. If the problem still exists, try using a different power sensor to determine if the problem is in the power meter or in the power sensor.
CAUTION: Electrostatic discharge will render the power sensor inoperative. Do not, under any
circumstances, open the power sensor unless you and the power sensor are in a static free environment.
Repair of Defective Sensor
There are no serviceable parts inside the E44XX-Series sensors. If the sensor is defective, replace the entire “module” with the appropriate “Restored Sen­sor Module.” See Table 6.
Cleaning
Cleaning Solutions
Keeping in mind its flammable nature; a solution of pure isopropyl or ethyl alcohol can be used to clean the connector.
Connector Cleaning
CAUTION: The RF connector beads deteriorate when contacted by hydrocarbon compounds
such as acetone, trichloroethylene, carbon tetrachloride, and benzene.
CAUTION: Clean the connector only at a static free workstation. Electrostatic discharge to the
center pin of the connector will render the power sensor inoperative.
Clean the connector face using a cotton swab dipped in isopropyl alcohol. If the swab is too big use a round wooden toothpick wrapped in a lint free cot­ton cloth dipped in isopropyl alcohol. Refer to Agilent Application Note 326, Principals of Microwave Connector Care (5954-1566) or Microwave Connector Care (08510-90064) for proper cleaning methods.
