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”.

Compatible power sensors:

• Agilent 8483A & 8480D Series

• Agilent E9300 E–Series

• Agilent E4410 E–Series

• Agilent N8480 Series

• Agilent U2000 Series

Frequency range: 9 kHz to 110 GHz, sensor dependent

Power range: –70 dBm to +44 dBm (100 pW to 25 W), sensor dependent.

Single sensor dynamic range:

• 90 dB maximum (Agilent E- Series power sensors)

• 50 dB maximum (Agilent 8483A & 8480D Series power sensors)

• 55 dBm maximum (Agilent N8480 Series power sensors)

• 80 dBm maximum (Agilent U2000 Series USB power sensors)

Display units:

Absolute: Watts or dBm.
Relative: Percent or dB.

Display Resolution

Selectable resolution of: 1.0, 0.1, 0.01 and 0.001 dB in logarithmic mode, or
1, 2, 3 and 4 significant digits in linear mode

Default Resolution

0.01dB in logarithmic mode or three digits in linear mode

Zero Drift of Sensors

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 Table 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

1 mW Power Reference

Power output:

1.00 mW (0.0 dBm). Factory set to ±0.4 % traceable to the National Physical
Laboratories (NPL), UK

Accuracy (for two years):

±0.4 % (25 ±10 ºC)
±1.2 % (0 - 55 ºC)

Frequency: 50 MHz nominal

SWR: 1.05 (typical), 1.08 (0 - 55ºC)

Connector type: Type N (f), 50 W

Accuracy

Absolute accuracy: ±0.02 dB (Logarithmic) or ±0.5% (Linear). Please add the

corresponding power sensor linearity percentage from Tables 6, 9 and 10 (for
the E-Series sensors), Table 14 (for the 8480 series sensors) and Table 16 (for
N8480 sensors) to assess the overall system accuracy.

Relative accuracy: ±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.

Zero Set (digital settability of zero):

Power sensor dependent (refer Table 1), this specification applies when
zeroing is performed with the sensor input disconnected from the
POWER REF.

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 the 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.

E-Series power sensor specifications

The E-Series of power sensors have their calibration factors stored in EEPROM and operate over a wide dynamic range. They are designed
for use with the EPM Series of power meters and two classes of sensors are available:

• CW power sensors (E4412A and E4413A).

• Average power sensors (E9300 sensors).

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.

Reflection coefficient (Rho) relates to the
SWR according to the following formula: SWR
= 1 + Rho/1 – Rho.

Maximum uncertainties of the CF data are
listed in table 5a, for the E4412A power
sensor, and table 5b 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
a 95% confidence level and a coverage
factor of 2.

The chart in Figure 1 shows the typical

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:

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.

E-Series E9300 average power sensor specifications (continued)

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.

Switching point linearity: Typically =±0.5%
(=±0.02 dB)

Switching point hysteresis: 0.5 dB typical

Calibration factor (CF) and
reflection coefficient (Rho)

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. The CF corrects for the
frequency response of the sensor. The EPM
Series power meter automatically reads the
CF data stored in the sensor and uses it to
make the corrections.

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

SWR = (1 + Rho)/(1 - Rho)

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 95% confidence level and a coverage
factor of 2.

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.
