The R&S ENV216 two-line V-network for disturbance voltage measurements on single-phase EUTs

Features

Air-core design and artificial hand

The R&S ENV216 two-line V-network is based on air-core inductances and contains an artificial hand.

Switch-selectable high pass filter of 150 kHz

To prevent the measuring receiver from being overdriven by low-frequency spectra of high level, a 150 kHz highpass filter can be cut in.

Built-in 10 dB attenuator pad

To ensure standard impedance irrespective of the receiver input attenuation, the R&S ENV216 is equipped with a 10 dB attenuator pad.

Built-in pulse limiter (can be switched off)

A built-in pulse limiter which can be switched off protects the receiver input.

Remote control with TTL levels (compatible with Rohde & Schwarz measuring receivers)

TTL control inputs that can be driven by controllers and Rohde & Schwarz measuring receivers are provided for remote control in automatic test systems (phase selection and activation of highpass filter). Optocouplers prevent pick-up of external disturbance.

Key facts

A female connector with protective earth contacts is provided for connecting the EUT. Various models with country-specific connector systems are available.

Owing to its compact design and low weight, the R&S ENV216 is ideal for frequently varying applications and especially for on-site disturbance voltage measurements on single-phase EUTs. Note that high leakage currents are produced because of the standard design of these V-networks. The networks should therefore be connected to a low-impedance protective earth system. In uncertain cases, an isolating transformer should be used

R&S FPC Key Features:

• RF performance engineered in Germany
• 10.1″ WXGA (1366 × 768 pixel) display – largest and highest resolution in its class
• Frequency range from 5 kHz to 1 GHz,  upgradable to 2 GHz/3 GHz
• Resolution bandwidth settings down to 1 Hz
• Tracking generator and independent CW signal generator
• Built-in VSWR bridge
• One-port vector network analyzer with Smith chart display
• Wi-Fi-enabled, supported by included remote control software
• 3 year standard warranty

The R&S FPC is the only spectrum analyzer on the market that provides the value of three instruments in one. And these are the three most commonly used instruments on an RF engineer’s workbench.

Spectrum analyzer

The R&S FPC1500 base instrument has a frequency range from 5 kHz to 1 Ghz with options to unlock up to 3 GHz and other features.

Engineered in Germany, it provides the best dynamic range in its class. In combination with RBW settings down to 1 Hz, it resolves the finest details, which are displayed on the high-resolution 10.1” WXGA display. Wired or wireless remote control options are available free of charge.

Vector Network Analyzer

The R&S FPC is a vector network analyzer that utilizes an integrated VSWR bridge to achieve one-port vector network analysis, with a Smith chart display available. Having an integrated VSWR bridge means there is no need to mount/dismount an external bridge during test operation.

Signal Generator

The R&S FPC is a signal generator due to the unique independent source principle. Not only does it provide standard tracking generator functionality, it can also be used in free or coupled CW modes.

The advantages of this three-in-one concept allows only one bench space to be occupied. A single instrument also means that to obtain the specified measurement performance, only a single investment and a single calibration are required.

High Resolution Display

The R&S FPC has the largest, highest-resolution display of any entry level spectrum analyzer. More horizontal plus more vertical display size and resolution means more signal details in unprecedented clarity. This class-leading display of the R&S FPC visualizes the outstanding quality of the signal measurements.
The quality of RF measurements strongly depends on suitable resolution bandwidth settings. Finer resolution bandwidth means more resolved spectral detail. High sensitivity is critical in many applications, e.g. when measuring extremely weak signals. The R&S FPC provides an extraordinarily low noise floor of typ. –150 dBm with 1 Hz resolution bandwidth setting.
The optional R&S FPC-B22 preamplifier increases sensitivity even further, to typ. –165 dBm. While most entry level spectrum analyzers can measure up to +20 dBm (100 mW), the R&S®FPC is able to measure high-power signals of up to +30 dBm (1 W).
The combination of low noise floor and high max. input power provides an exceptionally wide measurement dynamic range in the R&S FPC.

all available with and without tracking generator

Lightweight and compact for on-site installation, maintenance and service

The low weight (< 8 kg), the small size and the ruggedized housing make the R&S FSL ideal for mobile  applications. Due to these properties it is easy to carry to remote or hard-to-reach locations. The carrying bag with space for an extra battery pack and accessories and the protective hardcover are also very convenient for field use.
Optional internal battery pack for cordless use When equipped with the optional internal battery pack (R&S FSL-B31), the R&S FSL can be used independent of the mains supply for at least one hour. Easy and fast battery exchange in the field increases battery operation time. In addition, a DC power supply (R&S FSL-B30) is available for the R&S FSL. This option allows the R&S FSL to be used anywhere where DC power is available, e.g. in a car.

Power measurements with R&S NRP-xx power sensors

Another special feature of the R&S FSL is the fact that you can directly connect a power sensor from the R&S NRP series. The R&S FSL-K9 option and a connected power sensor allow very precise measurements of the DUT power – an enormous advantage for applications where level accuracy is crucial. The R&S FSL can thus replace a power meter. This is particularly important in mobile applications.
