87050A Option K24 System Setup System Setup The test set is designed to be placed underneath the network analyzer in a rack system and connected as shown in Figure 8. Use the two SMA 50 Ω jumper cables (08720-20245) included in the shipment. See Table 1 on page 3. Figure 8 Connecting the Test Set to the Network Analyzer After all the proper connections have been made, turn on the test set using the front panel line switch.
87050A Option K24 System Setup Setting the Test Set Address Switch The test set is shipped with the GPIB (HP-IB) address set to 12, which sets the parallel address to 0 as in Figure 9. Refer to “Operation” on page 18 for the definition of the parallel address. To set the GPIB address, set all five switches so that the sum of the switches in the On or “1” position equal the desired address. In the example below, the two switches in the “On” position are 8 and 4, therefore the GPIB address is 12.
87050A Option K24 System Setup Performance Verification For information on how to control the test set, refer to “Operation” on page 18. The following performance verification is designed to provide you with a high degree of confidence that your test set is working properly. It is not designed to verify specifications. To verify specifications, refer to “Performance Tests” on page 30. Equipment Required • Network Analyzer, 50 Ω impedance (Agilent 8720D) • Cable, 50 Ω 3.
87050A Option K24 Operation Operation The Agilent 87050A Option K24 is a “slave” instrument: a controller must be used to control the test set.
87050A Option K24 Operation Figure 10 Controlling the Test Set Over GPIB NOTE Connection to the network analyzer is not required when controlling the test set over GPIB. Network Analyzer Control The third method of sending commands uses the network analyzer to control the test set directly. This method is performed with the standard setup of the network analyzer working with the test set. A parallel cable is connected from the network analyzer output to the test set input on both rear panels.

87050A Option K24 Operation Calibrating the Test System After the test set has warmed up for at least two hours, you should calibrate before making any measurements. Refer to your network analyzer user’s guide to determine the type of calibration appropriate for the measurements you will be making. You must calibrate each measurement path separately and store the calibration as an instrument state in the network analyzer.
87050A Option K24 Operation Making Measurements The following examples assume that you are using a parallel port connection with an 8720D, with the test set's parallel address set to "0". See “Setting the Test Set Address Switch” on page 16 for information on setting the test set address. Measuring Reflection By leaving the DUT connected, as shown in Figure 12, and setting the network analyzer to measure S11, you can measure reflection or return loss.

87050A Option K24 Theory of Operation Theory of Operation The theory of operation begins with a general description of the 87050A Option K24 Multiport Test Set. This is followed by more detailed operating theory. The operation of each group is described briefly, to the assembly level only. Detailed component level circuit theory is not provided. System Theory The test set consists of three main components: a power supply, a front panel display and a controller interface mother board.
87050A Option K24 Theory of Operation Each path is routed to a bank of four 1 × 6 switches, for a total of eight 1 × 6 switches. Each bank of switches is routed to a single 1 × 4 switch where it becomes either the Transmission or Reflection port. All switches are mechanical, biased according to the necessary switching path. A user interface through the GPIB and parallel ports converts the necessary input signals from the user to the necessary control signals to control the switching paths.
87050A Option K24 Performance Tests Performance Tests Performance testing consists of measuring insertion loss, return loss and isolation between all ports. For the most accurate measurements, the use of an Agilent 8720D 50 Ω Network Analyzer is recommended and its use is recommended in this document. Familiarity with RF/microwave measurements is assumed. The use of adapters may be required and their effects should be accounted for.
87050A Option K24 Performance Tests Return Loss This test will verify the internal termination load of each port and the through match when the appropriate input port is terminated with a load. Step 1. Perform a one-port reflection calibration at the end of a 50 Ω cable over the frequency range of 50 MHz to 20 GHz on the analyzer. Verify the calibration is active and that the terminated cable displays a return loss of 0 (± 0.2 dB). Step 2.
87050A Option K24 Performance Tests Performance Test Record NOTE The following pages (Performance Test Record) are designed to be duplicated and used as a template for either of the Transmission or Reflection ports during each of the performance tests (Insertion Loss, Return Loss, and Isolation). At the top of each page, circle the appropriate input port (Transmission or Reflection), and write in the test date.
