Reference Info: Sample rate is 500 kHz (ADC clock rate).
1/500kHz = 2 μs per reading.
1 measurement = 125 readings.
125 readings/measurement * 2 μs/reading = 250 μs/measurement.
250 μs are added to account for data transfer from the sensor to the PC and CPU interrupts
(typical CPU and transfer time is <100 μs). 250 μs/measurement + 250 μs (transfer time and

The procedure applies to sensors that are in good working order, fully functional,
and without mechanical defect or damage. If there is any question about the
serviceability or functionality of the sensor, consult the User’s Manual to ascertain
the state of the sensor or contact Tektronix for advice. This procedure consists
of six steps:
1. Select the Test Record
2. Physical and functional check of DUT
3. Warm up
4. Match Test
Performance Verification
Required Equipment
5. Absolute Level
6. Linearity Test
As with any procedure, it is impractical to verify all conditions and states. So, the
procedure tests a selected set of measurement points. These points are sufficient to
ensure a high level of confidence in the sensor’s continued performance. As with
all calibration procedures, there is great reliance on the experience, knowledge,
sound judgment and skill of those doing the work.
Finally, if, during the calibration procedure, the sensor fails at any point, follow
local procedures for recording and resolving the problem before proceeding.
This section lists the equipment required for the calibration procedure. This
procedure refers to equipment by “NAME” rather than model number. So, rather
than refer to an “ Agilent N5183A” (see Table 1) the calibration procedure refers
to “SOURCE”. This term, “SOURCE”, comes from the Required Equipment
List below.
Like most calibration procedures, this procedure assumes access to common
hardware such as precision adapters and high quality cables. This hardware is
not called out in the equipment list. Nor is it depicted in the setup diagrams.
Nonetheless, it is required.
This procedure applies to several sensors with both 3.5 mm male and N-type male
input connectors. The required equipment varies depending on input connector.
Other equipment varies by DUT model number. Pay special attention to the type
of DUT you are calibrating when selecting your equipment.
Accuracy Test
If you choose to substitute equipment, consult the equipment list for information.
Be aware of the test range for each sensor. The test ranges for each sensor are
shown below:
PSM3110: 10 MHz – 8 GHz
PSM3120: 10 MHz – 8 GHz
PSM3310: 10MHz–18GHz

When selecting y our equipment be sure to check the equipment for damage or
excessive wear. SWR or match is the single biggest contributor to error and
uncertaint
y in power measurements. Using worn or damaged connectors during
calibration can induce “false failures”.
Thesameadv
ice applies when selecting cables. Use high quality cables during
calibration and ensure they are in good working order. When building the setups,
keep cables as short as possible. Keep any strain on the cables at a minimum.
If you choose to substitute any of the passive devices (adapters, attenuators, or
splitters) pay close attention to the specified SWR or match. Selecting components
with marginal performance will degrade the quality of the measurements. Note
that the limits on the Test Records take into account the published uncertainties
in the reference sensor, cal sensor, DUT, port tracking error in the splitter, and
mismat
ch errors.
