Option HL1 Microwave Preselector Bypass (MPB) and Low Noise
Path (LNP) Retrofit Kit
Introduction
This installation note explains how to install the hardware, and provides guidelines for adjustment
and verification for Option MPB, Microwave Preselector Bypass, and Option LNP, Low Noise Path.
Please note that the Option HL1 kit designator is only an ordering number.
Option MPB provides mechanical switches and associated hardware that bypass the A12 YTF (YIG
Tuned Filter). The YTF limits the bandwidth of the input signal and also this filter can drift causing
slight amplitude errors.
Option LNP provides a mechanical switch and associated hardware to bypass the A11 Low Band
Assembly when the instrument is tuned to frequencies above 3.6 GHz (High Band path). The A11
Low Band assembly contributes loss to the input signal path and reducing this loss improves the
Display Average Noise Level of the instrument. SHI performance increases also.
Products Affected: PXA N9030B, Option 508, 513, and 526
Serial Numbers: All
To Be Performed By: (X) Keysight Service Center
(X) Personnel Qualified by Keysight
( ) Customer
Estimated Installation Time:

The instrument must be readjusted and the performance tested to assure the instrument meets
specifications following the hardware installation. The X- Series Performance Verification and
Adjustment Software must be used. All adjustments are automated. This software is included in
the N7814A performance test & adjustment software package revision E.16.00 or greater.
The option is licensed for one instrument model number/serial number combination. The license
file that is downloaded from the web will only install on the designated instrument.

Initial Instrument Functionality Check
Power on the instrument and allow the instrument to boot up. Run an alignment and display the
measurement screen. (The instrument will probably display a spectrum analyzer screen and you will
see the instrument sweeping.)
There should be no alignment failures. If there are failures, investigate and fix the problem before
continuing.
Before you disassemble the instrument, turn the power switch to Standby and unplug the
instrument. Failure to unplug the instrument can result in personal injury.
Electrostatic discharge (ESD) can damage or destroy electronic components. All work on
electronic assemblies should be performed at a static-safe workstation. Refer to the
documentation that pertains to your instrument for information about static-safe workstations
and ordering static-safe accessories.

License Installation Procedure over USB
1. Locate the Option Upgrade Entitlement Certificate (5964-5178) from the kit.
2. Redeem the Option Upgrade Entitlement Certificate by following the instructions on the
Certificate.
3. After redeeming your Option Upgrade Entitlement Certificate you will receive an email with an
attached License File.
4. Locate a USB storage device. Perform a virus scan on this device before use.
5. Save the License File to the root directory of the USB Storage Device.
6. Connect the USB Storage Device to the signal analyzer USB port. Windows will detect the new
hardware and may display the configuration menu shown in Figure 13. This menu may be
configured according to your preferences.
Figure 13 USB Storage Device Configuration Menu
7. The signal analyzer will automatically consume the License File. (This may take a few minutes)
When the License File is consumed the Keysight License Manager will display a “Successful
License Installation” message similar to the one shown in Figure 14.
Even though the retrofit kit was ordered as Option HL1, the kit installs instrument options MPB
and LNP. The license file mentioned below will install both option MPB and LNP.

performance verification testing. Information on how to obtain this software can be found at
http://www.keysight.com/find/calibrationsoftware
Utilities Required
None
Adjustments Required
Performance Tests Required
A full calibration is required to assure the instrument meets all specifications
