What about RIGOL battery and portable use? Can you run RIGOL Scopes and Spectrum Analysers from Battery or portable UPS Power Supplies?
Last Updated: 14/08/2014

Running the DSA815 from a battery (see also comment about other instruments)

Although the size and weight of the DSA800's make it attractive for use in locations where there is no power, it suffers from the lack of an internal battery. A Google search uncovers a raft of battery backed up power supplies but the recommendation is that the DSA800's run from a supply that has a sine output. For this report, a DSA800 was connected to such a supply, the ac plug was pulled, and the Spectrum Analyzer's performance measured. For comparison, the instrument's performance was also monitored as it was running from an ac plug in the lab. The test results are at the end of this report.

The first group of test parameters were:

Start Freq 50 Mhz

Stop Freq 51 Mhz

Resolution Bandwidth 100 Hz

Reference Level -56 dBm

Preamplifier ON

The second group of test parameters were:

Center Freq 750 MHz

Span 1 Mhz

Resolution Bandwidth 100 Hz

Reference Level -56 dBm

Preamplifier ON

A Rigol DG4162 Function Generator was programmed to output a 50 MHz 0dBm signal and connected to the DSA800 input. The DSA800 was then configured to measure the function generators phase noise.

Before removing the power to the Battery Backed Up supply, the DSA800's tracking generator was turned on. After running for about 90 minutes, the DSA Stopped Running.

Summary:

The images below document that it would be very hard to differentiate the power source option used with the DSA800 by looking at the performance curves. It should be noted again that the Battery Backed Up Power Supply (CyperPower 100PFCLCD) has been designed to output a sine wave.

Although not tested, it's likely the Power Supply could be used with other Rigol Equipment. The Data Sheet for the Power Supply is at the end of this document.

PFC SINEWAVE SERIES

The CyberPower CP1000PFCLCD PFC Sinewaveuninterruptible power supply (UPS) with pure sine wave output and

multifunction LCD safeguards mid- to high-end computer systems, servers and networking hardware that use conventional

and Active Power Factor Correction (PFC) power supplies. Its automatic voltage regulation (AVR) topology delivers clean and

consistent AC power, protecting connected equipment and preventing costly business interruptions. Its patented GreenPower

UPSadvanced circuitry reduces UPS energy costs by up to 75% compared to competitive models.

The CP1000PFCLCD unit has a capacity of 1000VA/600Watts, ten (10) NEMA 5-15R receptacles and on (1) maintenancefree,

user-replaceable 12V/9Ah batteries. The intelligent multi-function LCD panel displays real-time UPS vitals for ease of

control. This unit offers connectivity via one (1) HID USB and one (1) DB9 serial ports. Protection for phone/network (RJ11/

RJ45) and cable/coax (RG-6) is included. EMI/RFI filters increase the immunity of the load to noise disturbances.

Intelligent LCD Diagnostic Display: The innovative front

white LCD panel displays UPS vitals: input voltage level,

output voltage level, automatic voltage regulator, battery capacity,

energy-saving bypass mode, runtime estimate, load

level, output frequency, on battery, overload, fault condition,

event logging, and silent mode.

PowerPanel® Personal Edition: In event of a power

outage, PowerPanel PE saves open files and “hibernates”

the PC to increase the run-time on the UPS unit. Power-

Panel is easily installed on any Windows-based PC and

uses minimal system resources. Diagnostic screens display

the status of the UPS, including silent operation mode,

configurable system notifications, automatic self tests,

adjustable high/low voltage warnings, event/data logging,

and scheduled shutdowns.

Technical Support: CyberPower assists users with any

product, installation, or warranty concerns – free of charge.

3-Year Warranty: Stringent manufacturing processes and

innovative product design enables CyberPower to offer one

of the strongest warranties in our industry. CyberPower will

repair or replace damaged units within three (3) years of

purchase date.

ISO & Safety Certifications: All CyberPower manufacturing

facilities are state-of-the-art and ISO-9001 Quality Tested.

Our products are certified by the FCC, cUL, and UL.

Windows Compatibility: Our PowerPanel® power management

software has been fully tested and is compatible with

Windows 2000, 2003, XP 32/64, Vista 32/64, 7, and

Server 2008.

Pure Sine Wave: When operating on battery, the PFC

Sinewave UPS outputs power with a pure sine wave that is

identical to or cleaner than the power from the utility company

grid, free of harmonic distortion and electrical noise,

resulting in optimal line clarity.

Automatic Voltage Regulation: AVR technology stabilizes

the AC voltage and maintains a safe voltage level without

switching to battery-mode. This conserves battery life, and

delivers cleaner AC power to connected equipment.

Energy-Saving Technology: Patented GreenPower UPS

advanced circuitry reduces UPS energy costs by up to 75%

compared to competitive models.

Tamper-proof Power Button: The Power button has been

specifically designed to minimize the chance the UPS can

be turned off or interfered with by accident.

EMI/RFI Filters: Filters against electromagnetic interference

and radio frequency interference ensuring clean power for

connected equipment.

Audible Alarms: Distinctive tones identify when the unit

is running on battery power, if it is overloaded or when the

battery is low.

Resettable Circuit Breaker: Convenient unit reset switch

in case of an overload.

USB Connectivity: HID compliant USB port enables full

integration with built-in power management and auto shutdown

features of Windows, Linux and Mac OS X.

Ultra-Quiet UPS: Advanced efficiency design (reduced fan

operation), high-end system components, and GreenPower

UPS technology help minimize sound emissions.
