N1913A/14A EPM Series Power Meters Performance Characteristics
Specifications describe the instrument’s warranted performance and apply after a 30 minute warm-up. These specifications are valid over its operating/ environmental range unless otherwise stated and after performing a zero and calibration procedure.
Supplemental characteristics (shown in italics) are intended to provide additional information, useful in applying the instrument by giving typical (expected), but not warranted performance parameters. These characteristics are shown in italics or labeled as “typical”, “nominal” or “approximate”.

±0.04 dB (Logarithmic) or ±1.0% (Linear). Please add the corresponding power sensor linearity percentage from the mentioned tables above to assess the overall system accuracy.
Power sensor dependent (refer Table 1), this specification applies when zeroing is performed with the sensor input disconnected from the POWER REF.
This parameter is also called long term stability and is the change in the power meter indication over a long time (within one hour) at a constant temperature after a 24-hour warm-up of the power meter. Sensor dependent, refer to Table 1. For E9300 sensors, refer to Table 11 for complete data.
Measurement noise
Sensor dependent, refer to Tables 1 and 2. For E9300 sensors, refer to Table 11 for complete data.
Effects of averaging on noise Averaging over 1 to 1024 readings is available for reducing noise. Table 1 provides the measurement noise for a particular power sensor with the number of averages set to 16 for normal mode and 32 for x2 mode. Use the “Noise Multiplier” for the appropriate mode (normal or x2) and number of averages to determine the total measurement noise value.
For example: For an Agilent 8481D power sensor in normal mode with the number of averages set to 4, the measurement noise is equal to: (<45 pW x 2.75) = <124 pW

Measurement speed
Using remote interface (over the GPIB, USB or LAN), three measurement speed modes are available as shown, along with the typical maximum measurement speed for each mode.
With N1913A power meter • Normal: 20 readings/second
• x2: 40 readings/second
• Fast: 400 readings/second
With N1914A power meter The measurement speed is reduced, for example, with both channels in FAST mode, the typical maximum measurement speed is 200 readings/second.
Fast mode is for Agilent E-Series power sensors only.
Maximum measurement speed is obtained using binary output in free run trigger mode.

Calibration factor (CF) and reflection coefficient (Rho)
Calibration factor and reflection coefficient data are provided 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 EPM power meter automatically reads the CF data stored in the sensor and uses it to make the corrections.
For power levels greater than 0 dBm, add 0.5%/dB to the calibration factor uncertainty specification.

The chart in Figure 1 shows the typical uncertainty in making a relative power measurement, using the same power meter channel and the same power sensor to obtain the reference and the measured values. Example
A illustrates a relative gain (amplifier measurement). Example B illustrates a relative loss (insertion loss measurement). This chart assumes negligible change in frequency and mismatch occur when transitioning from the power level used as the reference to the power level being measured.
Example A:
P = 10(P)/10 x 1 mW
P = 10 6/10 x 1 mW
P = 3.98 mW
3% x 3.98 mW = 119.4 μW
Example B:
P = 10 (P)/10 x1 mW
P = 10 –35/10 x 1 mW
P = 316 nW
3% x 316 nW = 9.48 nW where
P = power in Watts and

Effects of change in temperature on linearity
Note: If the temperature changes after calibration and you choose not to re-calibrate the sensor, the following additional power linearity error should be added to the linearity specs in Table 9.
For small changes in temperature:
The typical maximum additional power linearity error due to small temperature change after calibration is ±0.15%/°C (valid after zeroing the sensor).
For large changes in temperature:
Refer to Table 10.

Switch point data
The E9300 power sensors have two paths as shown in Table 7. The power meter automatically selects the proper power level path. To avoid unnecessary switching when the power level is near the switch point, switching point hysteresis has been added.
E9300 “A” suffix sensors example:
Hysteresis causes the low power path to remain selected until approximately –9.5 dBm as the power level is increased, above this power the high power path will be selected. The high power path will remain selected until approximately –10.5 dBm is reached as the signal level decreases, below this power the low power path will be selected.

Typically = ±0.5% (= ±0.02 dB)

Calibration factor and reflection coefficient data are provided at frequency intervals 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 certificate of calibration (CoC) with the serial number on the power sensor you are using.

Reflection coefficient (Rho) relates to the SWR according to the following formula:

Maximum uncertainties of the CF data are listed in Tables 12a and 12b.
As the E-Series E9300 power sensors have two independent measurement paths (high and low power paths), there are two calibration factor uncertainty tables. The uncertainty analysis for the calibration of the sensors was done in accordance with the ISO Guide. The uncertainty data reported on the calibration certificate is the expanded uncertainty with a

N8480 Series Thermocouple Power Sensor Specifications
The N8480 Series power sensors (excluding Option CFT) measure power levels from –35 dBm to +44 dBm (316 nW to 25.1 W), at frequencies from 100 kHz to
50 GHz and have two independent power measurement range (upper and lower range).
Meanwhile, the N8480 sensors with Option CFT only measure power levels from –30 dBm to +44 dBm (1 μW to 25.1 W) in single range. Similiar to the
E-Series power sensors, the N8480 Series power sensors are also equipped with
EEPROM to store sensor’s characteristics such as model number, serial number, linearity, temperature compensation, calibration factor, and so forth.
This feature ensures the correct calibration data is applied by any compatible power meter connected with N8480 Series power sensor, and to ensure the accuracy of the measurements.

N8480 Series Thermocouple Power Sensor Specifications
(continued)
Switch point data
Switching point is applicable for standard N8480 Series power sensors only.
The N8480 Series power sensors have two power measurement ranges; a lower range and upper range. The power meter automatically selects the proper power range. To avoid unnecessary switching when the power level is near switching point, a Switching Point Hysteresis has been added.
Switching point hysteresis:
0.5 dB typical
Example of switching point hysteresis on N8481/2H power sensors, this hysteresis causes the lower range to remain selected until approximately 17.5 dBm as the power level is increased, above this power the upper range is selected.
The upper range remains selected until approximately 16.5 dBm as the signal level decreases, below this power the lower range is selected.
For more detailed specifications, refer to Agilent N8480 Series Thermocouple
Power Sensors, data sheet (5989-9333EN).
