These specifications are valid over its
operating/environmental range unless
otherwise stated and after performing
a zero and calibration procedure.
Supplemental characteristics

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

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).

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:
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
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
(where P = power in Watts,
Maximum uncertainties of the CF data are listed in Table 8a, for the E4412A
power sensor, and Table 8b 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.
and (P) = power in dBm)

E-series E9300 Average Power Sensor Specifications
The E-series E9300 wide dynamic range, average power sensors are designed for use with the EPM family of power meters.
These specifications are valid ONLY after proper calibration of the power meter and apply for CW signals unless otherwise
stated.
Specifications apply over the temperature range 0 ˚C to 55 ˚C unless otherwise stated, and specifications quoted over the
temperature range 25 ˚C ±10 ˚C, conform to the standard environmental test conditions as defined in TIA/EIA/ IS-97-A and
TIA/EIA/IS-98-A [1].
The E-series E9300 power sensors have two independent measurement paths (high and low power paths):
High Power Path: -10 to +20 dBm ("A" suffix sensors), +20 to +44 dBm ("B" suffix sensors) and 0 to
+30 dBm ("H" suffix sensors).
Low Power Path: -60 to -10 dBm ("A" suffix sensors), -30 to +20 dBm ("B" suffix sensors) and -50 to
0 dBm ("H" suffix sensors).
Some specifications are detailed for an individual measurement path.

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 10:
The typical maximum additional Power Linearity error due to temperature change after calibration, for small changes in
temperature, is ±0.15%/ ºC (valid after zeroing the sensor).
For large changes in temperature, refer to Table 11.

Figure 2 shows the typical uncertainty in making a relative power measurement, using the same power meter channel and
same power sensor to obtain the reference and the measured values, and assumes that negligible change in frequency and
mismatch error occur when transitioning from the power level used as the reference to the power level being measured.

E-Series E9300 Average Power Sensors
Switch Point Data:
The E9300 power sensors have two paths, a low power path covers: -60 to -10 dBm ("A" suffix sensors), -30 to +20 dBm
("B" suffix sensors), and -50 to 0 dBm ("H" suffix sensors). The high power path covers: -10 to +20 dBm ("A" suffix sensors), +20 to +44 dBm ("B" suffix sensors), and 0 to +30 dBm ("H" suffix sensors). 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 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 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 13A and 13B. 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.

For pulses greater than 30 W, the maximum average power (Pa) is limited by the energy per pulse (E) in W.µs according to Pa = 30-0.02 E.
Includes 11708A 30 dB attenuator for calibrating against 0 dBm, 50 MHz power reference. The 11708A is factory set to 30 dB ±0.05 dB at 50 MHz, traceable to NIST. SWR <1.05 at 50 MHz.
