PXA N9030A Functional Tests 1 Functional Tests Functional tests are tests of various instrument parameters that give a high degree of confidence that the analyzer is operating correctly. They are recommended as a check of analyzer operation for incoming inspection or after a repair. Measurement uncertainty analysis is not available for functional tests, and the analyzer is checked against limits that are wider than the published specifications. The functional tests are designed to test an analyzer operating within the temperature range defined by the analyzer specifications using a minimum set of test equipment. If a test does not pass, performance verification tests must be run to determine whether a problem exists.

Functional Tests Functional Test Versus Performance Verification Functional Test Versus Performance Verification Functional tests use a minimum set of test equipment to check a much smaller range of parameters (and a limited number of data points for each parameter) than do performance verification tests. Functional tests use limits that are wider than the published specifications; measurement uncertainty analysis is not available for functional tests. NOTE If a functional test does not pass, you must run performance verification tests to determine whether a problem exists. Performance verification tests span a wide range of instrument parameters and provide the highest level of confidence that the instrument conforms to published specifications. These tests can be time consuming and require extensive test equipment.

Functional Tests Contents of this Document Contents of this Document This chapter includes the following: — “Before Performing a Functional Test” on page 6 (what to do first). — “Test Equipment” on page 7 (a list of the equipment required for all of the tests). Subsequent chapters describe the following Functional Tests: — “Displayed Average Noise Level (DANL)” on page 11 — “Frequency Readout Accuracy” on page 15 — “Second Harmonic Distortion (SHD)” on page 19 — “Amplitude Accuracy at 50 MHz” on page 23 — “Frequency Response (Flatness)” on page 29 — “Frequency Response (Flatness), Preamp On” on page 35 — “Scale Fidelity” on page 41 Each functional test includes: — Test limits (pass/fail criteria) — A description of the test — The equipment required for the test — A figure showing how to connect the equipment — Step-by-step instructions — One or more tables in which to record the measurement results

Functional Tests Before Performing a Functional Test Before Performing a Functional Test 1. Ensure that you have the proper test equipment. 2. Switch on the unit under test (UUT) and let it warm up (in accordance with warm-up requirements in the instrument specifications). 3. Allow sufficient warm-up time for the required test equipment (refer to individual instrument documentation for warm-up specifications). 4. Ensure that the analyzer’s frequency reference is set to Internal: a. Press the Input/Output, More, Freq Ref In keys. b. If the Freq Ref In softkey does not show Internal, press the Freq Ref In softkey and select Internal. 5. Following instrument warm-up, perform the auto align routine: Press System, Alignments, Align Now, All. NOTE Functional test accuracy depends on the precision of the test equipment used. Ensure that all of the test equipment is calibrated before running a functional test.

PXA N9030A Functional Tests 2 Displayed Average Noise Level (DANL) Test Limits (with 0 dB input attenuation) See Table 2-1 on page 13 for values. The Displayed Average Noise Level (DANL) of the signal analyzer is measured across a 10 kHz frequency span at several center frequencies. The analyzer input is terminated into a 50Ω load. A test is performed to assure the measurement is not performed in the presence of a residual response. The measurement is then averaged, and the result is normalized to a 1 Hz bandwidth. Figure 2-1 DANL Test Setup Item Critical Specifications (for this test) Recommended Keysight Model Termination, 50Ω Type-N(m)a Frequency: 10 MHz to 18 GHz 909A Option 012 Termination, 50Ω 2.4 mm (f)b Frequency: 10 MHz to 50 GHz 85138B a. for Options 503, 508, 513, and 526 b. for Options 543, 544, and 550

Press Restart, then wait for Average/Hold to display 20/20. 5. Press View/Display, Display, then press Display Line, On. 6. Rotate the knob and set the display line at the average amplitude of the displayed noise floor by visual inspection. 7. Confirm that the measurement is performed on the analyzer noise floor and not on a residual response within the displayed 10 kHz span. NOTE Ignore the residual response if one appears when taking the measurement. 8. Enter the value of the display line as the Measured Average Noise Level at 10 MHz column in Table 2-1. 9. Normalize the measured value to a 1 Hz BW by adding 30 dB to the measured value. NOTE The 30 dB value is added because the formula used to calculate the value of the noise power in a 1 Hz BW when measured with a 1 kHz BW is: Normalized Noise = 10 Log (BW 2/BW 1) where BW 2 is the 1 kHz BW we measure and BW 1 is 1 Hz BW to which we want to normalize. Therefore, 10 Log (1000) = 30 dB, so the noise floor will be 30 dB lower in a 1 Hz BW. 10.Enter the normalized value of the displayed average noise level in Table 2-1.

Displayed Average Noise Level (DANL) Procedure 11.The value of the normalized displayed average noise should be less than the specification value. 12.Change the analyzer center frequency to the next value listed in Table 2-1. Press: FREQ Channel, Center Freq, [Table 2-1 Value], GHz 13.Repeat step 4 through step 12 to fill in the remainder of Table 2-1 for your analyzer frequency range.

PXA N9030A Functional Tests 5 Amplitude Accuracy at 50 MHz Test Limits Amplitude Accuracy should remain within 1.13 dB of the measured source value across the range of source levels and changes in resolution bandwidth. The Preamp (option P03, P08, P13, P26, P43, P44, P50) should remain within ±1.3 dB of measured values. A synthesized sweeper is used as the signal source for the test. The source amplitude is varied using the signal source amplitude control. The attenuation and resolution bandwidth are varied on the signal analyzer. The source amplitude is measured by the power meter and signal analyzer at each setting, and the values compared. The difference between each pair of measurements indicates the amplitude accuracy.

This test checks the scale fidelity of the instrument by maintaining a constant reference level and measuring signals of different amplitudes over most of the display range.
