1 Usage Information

855xxA/B Series CalPods and 85523B CalPod ControllerUsage Information

Setup and Use of Keysight 855xxA/B Series CalPods

To get the most out of your purchase, it is recommended that this User’s Guide be read carefully and completely.
This document provides information on 855xxA/B Series CalPods, explaining how to set up all software and hardware, how to confirm operation, and how to use with a PNA Microwave Network Analyzer.
855xxA/B Series CalPods eliminate errors due to cable or test system instability. CalPods simplify the process of recalibrating the PNA by not requiring the removal of the Device Under Test (DUT) or the physical connection of standards. This allows recalibrating from a remote location, such as when the DUT is used with very long cables in a temperature chamber or TVAC (thermal-vacuum) chamber.
855xxA/B Series CalPod Models:
• 85530B 20 GHz CalPod (Standard)
• 85531B 20 GHz CalPod (Temperature Characterized)
• 85532B 20 GHz CalPod (Thermal-Vacuum Environments)
• 85540A 40 GHz CalPod (Standard)
• 85541A 40 GHz CalPod (Temperature Characterized)
• 85542A 40 GHz CalPod (Thermal-Vacuum Environments)

PNA firmware option 302 is used for temperature compensated and thermal-vacuum CalPods, and provides accurate recorrection capabilities over the temperature range –30 to +80 °C. With firmware option 302, up to 48 CalPods can be controlled, but only four CalPods at a time can be recorrected.
Step 4. Load Temperature Characterization Data
The following process is required for 85531B, 85532B, 85541A, and 85542A Cal Pods. It is not required for an 85530B or 85540A CalPod since these models do not have Temperature Characterization data.
If your CalPod model is an 85531B, 85532B, 85541A/B, or 85542A/B, it is temperature compensated, and was shipped with a USB drive that has a matching serial number – refer to Figure 1-1., “USB
Drive Matches Serial Number on CalPod,” on page 1-12. The USB drive contains Temperature
Characterization data that must be loaded into the PNA. To do so, use the following procedure.
4.1 Insert the USB drive into any USB port on the PNA.
4.2 To access the Windows desktop when the PNA application is active, select File > Minimize Appli
cation.
4.3. Right-click on Start and select Explore.

Step 8. Configure the Hardware for a Calibration
Figure 1-2, “Basic Measurement Hardware Configuration for Calibration (2-Port DUT),” on page 1-19
shows a recommended, basic measurement hardware configuration for calibrating the PNA when measuring a 2-port DUT. For information on more complex configurations, see the 855xxA/B Series CalPod Information website at: http://na.support.keysight.com/calpod.
The following items may be required, depending on your measurement hardware configuration.
• RF Cables – required to connect each CalPod to a PNA port. CalPods work well with cable losses (one- way loss from CalPod to PNA test port) up to 20 dB. CalPods will also work with cable losses greater than 20 dB, but the recorrection performance may be degraded. Consult the 855xxA/B Series CalPod Performance Characteristics document (85523-90007) available at:
http://na.support.keysight.com/calpod/calpod_pc_85523-90007.pdf
• RF Adapters for the Device Under Test (DUT) – required if
the DUT connectors are not compatible
with the CalPod RF2 (2.92 mm male) connector.
• Calibration Kit or ECal – compatible with DUT connectors.
• (Optional) CalPod Drive Cable Extensions – The standard CalPod drive cable is 2 meters in length.
The 85554A CalPod drive cable extension provides an additional 10 meter length. These CalPod drive cable extensions can be cascaded.

Step 9. Perform Initial 2-Port Calibration
Information
• The instructions in this step assume that CalPods are connected to PNA Port 1 and Port 2, and that a 2-Port calibration is used.
• Most PNA calibration types may be used with CalPods. For details, see “Calibration Types Not Supported
by CalPods” on page 2-3.
• For information on PNA traces and channels, see the Quick Start section of the PNA Series Network Analyzer Help System (available online and stored in the PNA).
• Notes on the calibration:
— An ECal or a mechanical calibration kit may be used to perform the calibration. An ECal is preferred
because the RF cables can remain totally undisturbed during the calibration and initialization steps.
— When an ECal is used and multiple connections are required, order the steps such that the final step
is an ECal “Thru” state connection.
— When a mechanical calibration kit is used, take precautions to minimize cable movement. Leave the
final standards connected during the initialization step in the following procedure.
— When the ECal or calibration kit is a 2.4 mm connector type, use appropriate adapters on the CalPod
RF1 and RF2 connectors (2.92 mm) during calibration.
Procedure

ow titled "Calibration Refresh Module Configuration" using
either method below.
Method 1:
Method 2:
Using the PNA front panel HARDKEYS and [softkeys].
Press
CAL > [More] > [CalPod] > [CalPod]
Using the mouse and the PNA pull-down menus.
Response > Cal > CalPod > CalPod
Click
If a “Windows Security Alert” appears that is related to the etrak Api, select “Unblock.”
9.4 Assign CalPods to PNA Port 1 and Port 2 or confirm that the appropriate assignments already exist.
Click the down arrow to select from available CalPods for a given port.
It is important to activate the CalPod dialog window at this point to ensure the CalPods are in the “thru” state.
9.5 Close the CalPod dialog window.
9.6 Configure the measurement hardware for the initial calibration.
The initial calibration consists of performing a normal calibration (typically with an ECal module), and
1-20 User’s Guide 85523-90005
855xxA/B Series CalPods and 85523B CalPod Controller Usage Information
then transferring this correction array to the CalPods when the Initialize Channel command is performed in Step 9.8.
The configuration for the initial ECal calibration and CalPod channel initialization can be significantly different from the final measurement configuration. A short cable between the PNA test port and the CalPod – as shown in the following graphic – can be used for the initial calibration. For the measurement, an entirely different cable with greater length and higher loss can be substituted between the PNA test ports and the CalPods. Additionally, different adapters, and even switch matrices can be added after the initial calibration to enable a measurement configuration.
9.7 Setup the measurement parameters on the PNA.
• Preset the PNA.
• Set up a 2-port measurement channel with the desired parameters for your DUT, including:
— class (choose from S-parameters, source power cal and receiver power calibrations, scalar
and vector mixer measurements, gain compression for amplifiers and mixers, noise figure for amplifiers and mixers, noise figure for amplifiers or mixers, IMD measurements for amplifiers
or mixers, IMD spectrum mode) — start and stop frequencies (20 GHz CalPods are characterized from 100 MHz to 20 GHz; 40 GHz CalPods are characterized from 500 MHz to 40 GHz). — number of points
For best initial calibration results, use a 1 kHz or lower IF bandwidth with an averaging factor of eight. Sweep averaging is recommended. For the actual DUT measurements, the IF bandwidth and number of averages can vary.
9.8 Use either of the following methods to perform a full 2-port calibration on the PNA, using an ECAL module (for highest accuracy) or a mechanical calibration kit.
Method 1: Using the PNA front panel HARDKEYS and [softkeys].
Press Cal > [Start Cal] > [Cal Wizard].
User’s Guide 85523-90005 1-21
855xxA/B Series CalPods and 85523B CalPod ControllerUsage Information
Method 2: Using the mouse and the PNA pull-down menus.
Click Response > Cal > Start Cal > Cal Wizard.
• Follow the prompts in the calibration wizard to complete the calibration
• Select Save as User CalSet. Any file name that does not contain “calpod” may be used.
You must select Save as User CalSet (rather than “Finish”) to save the calibration in the channel 1 cal regist
er.
IMPORTANT
After completing the calibration, do not disturb any of the measurement hardware, until “Step 10. Initialize the CalPods” is completed, and the Initialize Channel operation has been performed on the CalPods. During this operation, the CalPods make a measurement requiring the same measurement hardware to properly initialize the CalPod correction arrays.
Step 10. Initialize the CalPods
Without disturbing any of the measurement hardware, use either of the following methods to save the initial calibration into the CalPod correction array. This must be done immediately after completing the last step of the initial calibration.
Method 1: Using the PNA front panel HARDKEYs and [softkeys].
Press CAL > [More] > [Calpod] > [Initialize Channel]
Method 2: Using the mouse and the PNA pull-down menus.
Click Response > Calpod > Initialize Channel
The calibration correction array established by the initial calibration is transferred to the CalPod correction array in this step. Any disturbances of the measurement hardware (such as cable movements) prior to performing the Initialize Channel step will affect the quality of the recorrection array.
IMPORTANT Do not Initialize Channel at any future point in time or the recorrection array will
be corrupted, causing improper recorrections and inaccurate measurement data.
Step 11. Configure the Hardware for a Measurement
After the Initialize Channel procedure is completed, as detailed in the previous step, the measurement hardware can be reconfigured. For example, the short, stable cable between PNA port 1 and the CalPod can be replaced with a longer cable to reach a CalPod and DUT located inside a temperature or TVAC chamber. Other modifications in the path between the PNA and the CalPod – such as different adapters, and even switch matrices – can now be made.
Step 12. Recorrect (Refresh) the CalPods
When a calibration refresh is performed, the initial calibration is reestablished at the new location of the CalPods.
1-22 User’s Guide 85523-90005
855xxA/B Series CalPods and 85523B CalPod Controller Usage Information
12.1 Connect the CalPods to the DUT and recorrect the calibration using either of the following methods.
Method 1: Using the PNA front panel HARDKEYs and [softkeys].
Press CAL > [More] > [Calpod] > [Recorrect Channel]
Method 2: Using the mouse and the PNA pull-down menus.
Click Response > Cal > Calpod > Recorrect Channel
The system is now ready to make calibrated measurements on
the DUT.
12.2 When you want to reestablish the initial calibration, refresh the calibration using either of the methods above. Some examples of situations that call for a calibration refresh:
• Moving the location of the CalPods and DUT. For example, moving them from close proximity with the PNA to inside a temperature or thermal-vacuum chamber.
• Changing cables, cable lengths, or connectors in the path between the PNA and the CalPod.
• Adding a switch matrix or adaptors in the path between the PNA and the CalPod.
• Changing switch positions in a switch matrix.
• Changing temperatures inside of a temperature or thermal-vacuum chamber where the
CalPod and DUT are located.
• Moving or flexing the cables.
• Wanting to be certain that a valid calibration is present at the calibration plane.
Step 13: Measure the DUT
Gather data from the PNA measurement of the DUT.

Configuration: Control Through a TVAC Chamber Wall
Thermal-vacuum testing requires controlling the CalPods inside of a TVAC chamber using an 85554A CalPod drive extension cable. This cable is cut to the appropriate length, and the cable conductors soldered to an appropriate TVAC bulkhead connector to provide DC connections through the TVAC chamber wall. Alternatively, Pave Technology (www.pavetechnology.com) has an SP37/13-E-150-15-20-DSUB-DSUB connector that is used for TVAC bulkheads. The control voltages are +/-15 Vdc with 60 mA per cable conductor.

Servicing
This product is designed for use in Installation Category II and Pollution Degree 2 per IEC standards.
Ventilation Requirements: When installing the instrument into a cabinet, consideration shall be given to the convection flow into and out of the cabinet. Consideration shall also be given to the individual instruments to avoid having the heated discharge of one instrument become the cooling intake air for another instrument. Another area of concern is verification that the maximum ambient operating temperature of the instrument is not exceeded due to cabinet installation. Keysight recommends forced air convection whenever an instrument is installed in a cabinet and further recommends that the maximum operating temperature of the cabinet be reduced 10 °C lower than the maximum operating temperature of a single instrument. If there are any concerns or special requirements, a Keysight Field Engineer should be consulted to assure instrument temperature compliance and performance.
These servicing instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing unless you are qualified to do so.
No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent electrical shock, do not remove covers.
The opening of covers or removal of parts may expose dangerous voltages. Disconnect the instrument from all voltage sources while it is being opened.
