Key Uses & Functions of Handheld Test Tools

Field Electrical Measurement

Measure voltage, current, resistance, and continuity in the field with CAT III / CAT IV-rated handheld DMMs designed for safe use in industrial and power distribution environments.

On-Site Signal Troubleshooting

Capture and analyze voltage waveforms on-site using battery-powered handheld oscilloscopes when benchtop instruments are not available or practical.

RF Site Survey and Interference Hunting

Locate RF interference, measure signal strength, and verify antenna performance at cell tower sites, broadcast facilities, and wireless installations using handheld spectrum analyzers.

Cable and Antenna Testing

Measure cable loss, distance-to-fault (DTF), return loss, and VSWR of antenna systems using FieldFox combination analyzers without returning to the lab.

Network Analysis in the Field

Perform S-parameter measurements on RF components and cables using handheld VNAs (FieldFox) for on-site verification and maintenance of RF infrastructure.

Passive Component Measurement

Measure inductance, capacitance, and resistance of passive components at frequencies up to 2 MHz using handheld LCR meters for incoming inspection and maintenance.

Frequently Asked Questions (FAQs)

Is Tekmark an authorized distributor for Keysight handheld test instruments?

Tekmark Sdn Bhd is an authorized Keysight Technologies distributor in Malaysia, Singapore, and the Philippines, carrying 121 Keysight handheld instruments including DMMs, oscilloscopes, FieldFox analyzers, and LCR meters. Verify on Keysight’s official Partner Finder.

Which Keysight FieldFox models does Tekmark carry?

Tekmark carries the N991x Series (up to 9 GHz), N992x Series (up to 26.5 GHz), and N993x Series (up to 44 GHz). FieldFox models are available as cable/antenna analyzers, spectrum analyzers, combination analyzers, or VNAs depending on option configuration. Browse all on the Tekmark e-shop.

How do I choose the right FieldFox model for my field testing needs?

Selection depends on your frequency range and required measurements. The N991x (up to 9 GHz) covers cellular, VHF/UHF, and public safety. The N992x (up to 26.5 GHz) adds microwave capability. The N993x (up to 44 GHz) handles 5G mmWave and automotive radar. Each model can be upgraded with additional measurement modes through licensed options. Tekmark can recommend the right model and option set for your budget.

How do I get a quote for Keysight handheld instruments from Tekmark?

Submit a request through Tekmark’s contact form or add instruments to your quote cart on the e-shop. For FieldFox, include the frequency range, required measurement modes, and quantity. For DMMs and oscilloscopes, include the model and unit count.

What warranty comes with Keysight handheld instruments from Tekmark?

Every Keysight handheld instrument from Tekmark includes full manufacturer warranty covering the instrument, battery, and standard accessories. Handheld instruments face more physical stress than bench equipment, making authorized warranty coverage especially important.

Can Tekmark support multi-unit procurement for field service teams?

Tekmark supports fleet purchases for organizations equipping multiple technicians with the same handheld model. 

For field electrical maintenance teams standardizing on a handheld digital multimeter or handheld multimeter, we can quote multi-unit packages across the U1230, U1240, U1270, and U1280 Series. Standardizing on a single FieldFox or DMM series simplifies training, ensures consistent procedures, and streamlines calibration scheduling.

What does Tekmark offer that an online electronics catalog does not?

FieldFox analyzers require configuration decisions at purchase: base model, frequency range, and measurement mode options. Tekmark’s engineers evaluate your field testing needs and recommend the right configuration, preventing overspend on unused options or underspecification that limits your field capability.

Equip Your Field Team with the Right Keysight Handheld Instruments

Whether you need a single FieldFox for RF site work or a fleet of handheld test tools and DMMs for your maintenance team, Tekmark's engineers will help you select and configure the right Keysight portable instruments.
