Z5602A Option H24/H35/H50/H51/H52
User’s and Service Guide 1
Z5602A Option H24/H35/H50/H51/H52 Description
Description
The Agilent Z5602A Precision Power Reference is a portable 50 MHz sine wave source that
requires a very short warm-up time. Traditionally, the process to determine the amplitude
accuracy of a source used to calibrate a device under test (DUT) involved power meter
measurements and associated calculations to determine the uncertainty of the power
meter, the interconnect cables and the VSWR effects of the power meter/source and
source/DUT. The Agilent Z5602A Precision Power Reference can achieve the same
accuracy as the calibration source built into a power meter, and mates directly with the
Type-N female connectors on the spectrum analyzer inputs. The Precision Power Reference
greatly reduces the measurement uncertainties mentioned above.
The Precision Power Reference is available in three different connector types: 2.5 mm,
3.5 mm and Type-N (m). Additionally, the Type-N version has 3 different power levels:
0 dBm, −25 dBm and −30 dBm. Each Precision Power Reference has a power cable that can
be directly connected to the probe power outlet (−12.6V, +15V) on a spectrum analyzer or
other instruments with the probe power feature.
The small size and portability of the Precision Power Reference increases the potential for
use in automated production test systems.
Verifying the Shipment
Verify that you have received the proper option items listed in Table 1. Inspect the
shipping container. If the container or packing material is damaged, it should be kept until
the contents of the shipment have been checked mechanically and electrically. If there is
physical damage refer to “Contacting Agilent Sales and Service Offices” on page 12. Keep
the damaged shipping materials (if any) for inspection by the carrier and an
Agilent Technologies representative.

Amplitude Accuracy
The PSA Series spectrum analyzer requires the Z5602A Option H24/H35/H50/H51 or H52
when adjusting the amplitude of the internal 50 MHz reference.
The following example illustrates how the Option H51 version of the Precision Power
Reference can be used to verify the amplitude accuracy of the Agilent E4440A Spectrum
Analyzer at 50 MHz.
Verify that the spectrum analyzer has been turned On for a minimum of 30 minutes.
Typeface Key Conventions
The following key conventions are used throughout this document.
• [HARDKEYS] are labeled front panel keys
• SOFTKEYS are unlabeled key whose function is indicated on the instrument display
Adjustment Procedure
Perform the following front panel keystrokes on the spectrum analyzer.
1. Press [SYSTEM] > Alignments > Align All Now to trigger an alignment on the
spectrum analyzer.
2. Connect the Precision Power Reference to the spectrum analyzer as shown in Figure 1
on page 3.
3. To view the Precision Power Reference signal, set the spectrum analyzer controls as
follows:
a. Press [Frequency] > [50 MHz > [Span] > [1 MHz] > [Single] > [Peak Search]
b. Compare the signal amplitude displayed on the spectrum analyzer to the power level
shown on the calibration sticker attached to the Precision Power Reference. For
example; the spectrum analyzer marker value may be −25.07 dBm and the
calibration sticker on your Precision Power Reference may indicate −25.009 dBm.
Therefore, the spectrum analyzer amplitude error is −0.061 dB.
