E8257D Option HAR Description
Description
The E8257D Option HAR is a frequency divider designed to provide improved phase noise
in the 0.98 MHz to 500 MHz frequency range of the E8257D Signal Generator.
The Option HAR uses frequency division as a replacement for heterodyne mixing to create
frequencies in the 0.98 to 500 MHz range. This provides improved phase noise in this
mode. The mode will be referred to as “Divider Mode” throughout this document.
Verifying the Shipment
After the unit has been unpacked, keep the original packaging materials so it can be
used if you need to transport the instrument.
After the test set has been unpacked, keep the original packaging materials so they can be
used if you need to transport the instrument.Inspect the test set and all accessories for any
signs of damage that may have occurred during shipment. If your test set or any
accessories appear to be damaged or missing refer to “Contacting Agilent Sales and Service
Offices” on page 26.

E8257D Option HAR Specifications
Specifications
The E8257D Option HAR provides improved absolute phase noise in the 0.98 to 500 MHz
frequency range. To achieve these improvements the Divider Mode must be turned On.
See “Operation” on page 8.
The E8257D Option HAR impacts standard instrument performance for frequencies
≤3.2 GHz. Standard operation for frequencies above 3.2 GHz has not been affected. If
Divider Mode is left on for frequencies outside of 0.98 to 500 MHz the “ALC Bandwidth”
will be limited to 100 Hz.

Troubleshooting
1. Before troubleshooting E8257D Option HAR, verify that the standard instrument is
operating properly with the Divider Mode Off. If not, troubleshoot in Standard Mode.
2. For the instrument to operate properly with the Option HAR circuitry installed (Divider
Mode On or Off), licenses are needed for the following options:
•OptionHAR
• Option 1EH
3. If the Phase Noise in Divider Mode is does not meet specification (refer to “Performance
Test” on page 11), replace the Divider Assembly.
4. Measure the losses through Option HAR in Standard Mode (Divider Mode Off).

5. If there is excessive loss in one path, replace the Divider Assembly.
6. If there is excessive loss in both paths, remove the ribbon cable from the Divider
Assembly and measure the following voltages at the end of the ribbon cable.
7. If any of the voltages are wrong, measure the same voltages on the Lowband Filter
Assembly (J6).
a. If the voltage at pin 25 is incorrect, measure the voltage on the motherboard at P142,
pin 7.
1. If the voltage at P142, pin 7 is < 8 volts, replace the Motherboard.
2. If the Motherboard is working properly, replace the Lowband Filter Assembly.
b. If the voltage on the Lowband Filter Assembly (J6) pin 23, 24 or 26 is incorrect.
1. Replace the Lowband Filter Assembly.
2. If the Lowband Filter Assembly is working properly, replace the ribbon cable from
the Lowband Filter Assembly to the Divider Assembly.
8. Set the instrument frequency to 1 MHz, Output power to maximum and RF On.
9. With all other cables connected, make the following measurements on the Divider
Assembly with a spectrum analyzer.
10.If the frequencies at connector P2 are incorrect.
a. Troubleshoot the standard synthesizer system.
11.If the amplitude at connector P2 is incorrect.
