Applies to 10 MHz. For impedance at higher frequencies see SWR diagram on page 4.
2)
Not with BNC adapter.
3)
Up to 40 MHz.
applies at higher frequencies.
4)
With BNC adapter (50
:
). 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 the 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 identical 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 uncertainty 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 measurement 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, i.e. at 33°C, 38°C
etc, for the ¸URV5-Z7 without plug-on divider between 20 kHz and 30 kHz, for the ¸URV5-Z2 between 9 kHz and 15 kHz and for the ¸URV5-Z4 between 100 kHz and 300 kHz.
12)

load. Specifications referenced 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 referenced to incident wave.
14)
With reflection-free load at the female connector,
frequency correction switched on, specifications referenced 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.
