Mai 2001 1:16 13 RF Probe URV5-Z7 The RF Probe is a universal tool for measuring RF voltages. The low input capacitance of 2.5 pF makes it virtu- ally non-loaded and ideally suitable for measurements on non-coaxial cir- cuits up to 500 MHz or up to 1 GHz when appropriate accessories are used. A plug-on divider extends the voltage measurement range from 10 V to 1000 V and at the same time reduces the input capacitance to 0.5 pF. Compared to active, high-impedance probes, the dynamic range of the URV5-Z7 is greater by a factor of 10 to 100, ie higher voltages can be measured with the same sensitivity. With a dynamic range from 200 µV to RF Probe URV5-Z7 10 V without the use of a plug-on divider, the probe covers all voltage 200 µV to 10 (1000) V levels common in state-of-the-art elec- 20 kHz to 1 GHz tronic equipment. 1.5 1.2 a dB b a b c 1 c 1.1 0.5 1 0 10 100 200 300 400 MHz 500 10 100 200 300 400 MHz 500 Frequency Frequency Typical frequency response of RF Probe URV5-Z7 with voltage measurements Typical SWR of a matched 50 Ω line after connecting RF Probe URV5-Z7 on a matched 50 Ω line (without adapter, short ground connection); (without adapter, short ground connection); a) direct, b) with 20 dB plug-on a) direct, b) with 20 dB plug-on divider, c) with 40 dB plug-on divider divider, c) with 40 dB plug-on divider 4 Voltage Sensors URV5-Z Frequency response SWR Urv5-z_de.fm Seite 5 Freitag, 18.

DC Probe URV5-Z1 The low input capacitance of the DC Probe URV5-Z1 makes it particularly suitable for measurements in RF cir- cuits.

Mai 2001 1:16 13 Insertion Unit URV5-Z2 Insertion Units URV5-Z2 and 200 µV to 10 V URV5-Z4 9 kHz to 3 GHz Insertion Unit URV5-Z4 The Insertion Units URV5-Z2 and 2 mV to 100 V URV5-Z4 are used for uninterrupted 100 kHz to 3 GHz level measurements between source and load and for terminated power measurements. Due to their wide fre- quency range they are ideal espe- cially for the measurement of EMC test levels as well as many general- purpose applications. Compared to the terminating power sensors of the NRV line the URV5-Z2 and URV5-Z4 insertion units offer a larger dynamic range, a much lower frequency limit (9 kHz with URV5-Z2) and the possibility of using them dur- ing operation of the load. Both units are made up of a short, coaxial line between the two RF con- nectors, in the middle of which the volt- age is tapped: directly with URV5-Z2, and via a capacitive 20 dB divider with URV5-Z4.

For impedance at higher frequencies see SWR diagram on page 4. 2 ) Not with BNC Adapter. 3 ) Up to 40 MHz. <210 V(rms)/√(f/GHz) applies at higher frequencies. 4 ) With BNC adapter (50 Ω). Maximum power limited by losses in the adapter. 5 ) Upper limit frequency depending on adapter and source impedance. 6 ) Up to 1.5 GHz. At higher frequencies the upper limit of the measurement range is to be reduced according to max.rating. 7 ) Up to 2 GHz. At higher frequencies the upper limit of the measurement range is to be reduced according to max.rating. 8 ) The insertion loss of Insertion Unit URV5-Z2 is level-dependent above 0.5 GHz. The specified values refer to low test voltages at which the highest loss is obtained. 9 ) Measurement uncertainty limits without consideration of correction values for the frequency-dependent response of RF probes. Measurement uncertainty limits are identi- cal with error limits, but with opposite sign. 10 ) Expanded uncertainty with a coverage factor k = 2, with the frequency-dependent correction values stored in the probe being taken into account. An expanded uncer- tainty with k=2 corresponds to a coverage probability of approx. 95 % for a normal distribution of combined errors. 11 ) In this frequency range the measurement accuracy is strongly voltage- and temperature-dependent. Therefore, at temperatures above 28°C an increase in the measure- ment uncertainty is to be expected that is far above the value specified for the temperature effect. In the worst case it can be assumed that the measurement uncertainty will double with every temperature increase of 5 K, ie at 33°C, 38°C etc, for URV5-Z7 without plug-on divider between 20 kHz and 30 kHz, for URV5-Z2 between 9 kHz and 15 kHz and for URV5-Z4 between 100 kHz and 300 kHz. 12 ) In BNC adapter terminated with 50 Ω load. Specifications referred to incident wave at source terminal. With mismatched load, measurement uncertainty limits may rise due to standing waves by about ±4 dB (SWR-1). The approximation refers to SWR of up to 1.25; for SWR = 1.2 the increase would be ±0.8 dB. 13 ) Specifications referred to incident wave. 14 ) With reflection-free load at the female connector, frequency correction switched on, specifications referred to incident wave at male connector. Due to standing waves, mismatch of the load can lead to an additional measurement uncertainty that can be approximated by 2.8 dB x (SWR-1) for the standard uncertainty (formula valid for SWR of up to 1.25). 15 ) Limited to the specified value for reasons of conformity with international safety standards. Deviating specifications on the type plates of older sensors are to be regarded as the maximum possible physical rating. Voltage Sensors URV5-Z 9 Urv5-z_de.fm Seite 10 Freitag, 18.
