Calibrating Before You Start

Before You Start

This brief procedure should be performed before starting the performance verification tests:

1. Switch the analyzer on and let it warm up for five minutes.

2. If the analyzer is an Agilent E4402B, E4403B, E4404B, E4405B, E4407B, or E4408B, connect a cable from AMPTD REF OUT to the

50 Ω Input.

3. Press alignments to finish.

4. Read the remainder of this section before you start any of the tests, and make a copy of the Performance Verification Test Record described below in "Recording the test results."

System, Alignments, Align Now, All, and wait for the auto

Recording the test results

Performance verification test records, for each analyzer, are provided in the chapter following the tests.

Each test result is identified as a TR Entry in the performance tests and on the performance verification test record. We recommend that you make a copy of the performance verification test record, record the test results on the copy, and keep the copy for your calibration test record. This record could prove valuable in tracking gradual changes in test results over long periods of time.

Performing Self-Alignment

Perform a complete self-alignment at least once per day, or if the analyzer fails a verification test. To perform a self-alignment, press

System, Alignment, Align Now, All. The instrument must be up to

operating temperature in order for this test to be valid. If the analyzer continuously fails one or more specifications, complete any remaining tests and record all test results on a copy of the test record. Then refer to Chapter 4 , “If You Have a Problem,” for instructions on how to solve the problem.

Manual use of Agilent 8494G and Agilent 8496G Attenuators with the Agilent 11713A

When using the programmable versions of the 1 dB and 10 dB step attenuator (Agilent 8494G and Agilent 8496G), the Agilent 11713A Attenuator/ Switch Driver must be used to control the attenuators. The Agilent 8494G 1 dB step attenuator should be connected as Attenuator X and the Agilent 8496G 10 dB step attenuator should be connected as Attenuator Y.

Use Table 2-2 to determine which of the Attenuator X and Attenuator Y settings are use to set the step attenuators to the desired value. In the columns labeled Attenuator X and Attenuator Y, a “1” indicates that section is on (the LED in the button will be lit), while a “0” indicates that section is off. For example, if the 1 dB step attenuator should be set to 2 dB and the 10 dB step attenuator should be set to 60 dB, sections 2, 6, and 7 should be on (lit) and all other sections should be off.

2. 10 MHz High-Stability Frequency Reference Output Accuracy: Agilent E4401B, E4402B, E4404B, E4405B, and E4407B (Option 1D5)

This test applies only to analyzers equipped with the high-stability frequency reference, Option 1D5. If your analyzer does not have Option 1D5, perform the “10 MHz Reference Output Accuracy” test instead.

This test measures the warmup characteristics of the 10 MHz reference oscillator. The ability of the 10 MHz oscillator to meet its warmup characteristics gives a high level of confidence that it will also meet its yearly aging specification.

The universal counter is connected to the 10 MHz REF OUT. After the analyzer has been allowed to cool for at least 60 minutes, the analyzer is powered on. A frequency measurement is made five minutes after power is applied and the frequency is recorded. Another frequency measurement is made 10 minutes later (15 minutes after power is applied) and the frequency is recorded. A final frequency measurement is made 60 minutes after power is applied. The difference between each of the first two frequency measurements and the last frequency measurement is calculated and recorded.

The related adjustment for this performance verification test is the “10 MHz Reference Frequency Adjustment.”

10. Residual FM

This test measures the inherent short-term instability of the analyzer LO system. With the analyzer in zero span, a stable signal is applied to the input and slope detected on the linear portion of the IF bandwidth filter skirt. Any instability in the LO transfers to the IF signal in the mixing process. The test determines the slope of the IF filter in Hz/dB and then measures the signal amplitude variation caused by the residual FM. Multiplying these two values yields the residual FM in Hz.

For instruments having Option 1DR (Narrow Bandwidths), since the 10 Hz resolution bandwidth filter is digitally implemented, its slope is well known. The measured amplitude variation is simply multiplied by the known slope to yield the residual FM in a 10 Hz resolution bandwidth.

There are no related adjustment procedures for this performance test.

A 50 MHz CW signal is applied to the input of the analyzer through two calibrated step attenuators. The attenuators are the amplitude reference standard. The source is adjusted for a response at the reference level. The attenuators are then set to achieve a nominal amplitude below the reference level. The analyzer amplitude marker is compared to the actual total attenuation to determine the scale fidelity error.

The test is performed in both log and linear amplitude scales.

The related adjustment for this performance test is “IF Amplitude.”

13. Input Attenuation Switching Uncertainty

A 50 MHz CW signal is applied to the input of the analyzer through two calibrated step attenuators. The attenuators are the amplitude reference standard. The source is adjusted for a response at the reference level. The internal attenuators are then varied between settings and the external attenuators are changed accordingly to maintain the same input level at the mixer. The analyzer marker functions are used to measure the amplitude differences. The actual attenuation values of the step attenuators are used to correct the marker amplitude readings yielding the input attenuation switching error.

The related adjustment for this performance test is “Frequency Response.”
