Measurement speed

Three measurement speed modes,
over the GPIB, are available as
shown, along with the typical maxi­mum measurement speed for each
mode.

With the E4418B power meter

Normal: 20 readings/second
x2: 40 readings/second
Fast: 200 readings/second

With the E4419B, the measurement
speed is reduced, for example, with
both channels in FAST mode, the
typical maximum measurement
speed is 100 readings/second.

Fast mode is for E-series sensors
only.

Maximum measurement speed is
obtained using binary output
and in free run trigger mode.

Zero drift of sensors: Sensor depen­dent, refer to table 2. For E9300
sensors, refer to table 12 for
complete data.

Measurement noise: Sensor depen­dent, refer to table 2 and table 3. For
E9300 sensors, refer to table 12.

Effects of averaging on noise: Averaging
over 1 to 1024 readings is available
for reducing noise. Table 2 provides
the measurement noise for a particu­lar sensor with the number of
averages set at 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.

Example:

8481D power sensor, normal mode,
number of averages = 4.

Measurement noise calculation:

(< 45 pW x 2.75) = < 121 pW.

E-series power sensor

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:

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,
and (P) = power in dBm)

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

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 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.

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):

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%/°C (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

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.
