Agilent N1913A and N1914A

As signals become more complex, it
becomes more difficult to make fast,
accurate power measurements. For
years, you’ve depended on Agilent’s
EPM Series power meters. Today,
the Agilent N1913A and N1914A
EPM power meters are versatile,
user-friendly replacements for the
E4418B/19B EPM Series. Best of
all, you get these extras for about
the same price as the EPM Series.
Get consistent results and greater
capability—with the new EPM power
meters.

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”.

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

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)

Zero drift of sensors This parameter is also called long term stability and is the change in the power meter indication

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

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

along with the typical maximum measurement speed for each mode.

With N1913A power meter • Normal: 20 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.

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

SWR = 1 + Rho/1 – Rho.

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:

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

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.

For more detailed specifications, refer to Agilent N8480 Series Thermocouple
Power Sensors, data sheet (5989-9333EN).

U2000 Series USB Power Sensor Specifications

The U2000 Series USB power sensors are true average, wide-dynamic-range
RF/microwave power sensors, based on a dual-sensor diode pair/attenuator/
diode pair topology.

The U2000 Series USB power sensors can be operated on N1913A/14A via the
USB host port (options).
