500 MHz Passive Probe, 5mm, 10:1, 10 MOhm
PP025-1
Passive probes are the standard probe provided with most oscilloscopes. Typical passive probes provide a 10:1 attenuation and feature a high input resistance of 10 MΩ. This high input resistance means that passive probes are the ideal tool for low frequency signals since circuit loading at these frequencies is minimized. Passive probes are designed to handle voltages of at least 400V, some as high as 600V. Teledyne LeCroy passive probes feature an attenuation sense pin which tells the oscilloscope to scale the waveforms automatically requiring no user input.Each passive probe is recommended for a certain oscilloscope, using the right passive probe with the right oscilloscope means that the probe will be properly compensated across the entire bandwidth. Using probes with a different oscilloscope will only let you compensate for low frequencies.

Dual Polarized Antennas
Dual polarized horn antennas are offered as both standard and custom models with rectangular waveguide interfaces for both horizontal and vertical ports. These dual polarized horn antennas support both linear and elliptical polarized waveforms. When the antenna receives a circular polarized waveform, equal amplitude linear polarized waveforms are output at both horizontal and vertical ports. When two equal amplitude linear polarized waveforms are input into the vertical and horizontal ports, the antenna will transmit a circular polarized waveform. The listed models offer 15 dB nominal gain and 33/28 degrees typical half power beamwidth at the center frequency of the band. They also exhibit 40 dB typical port isolation and 35 dB nominal cross polarization. These antennas cover full waveguide bandwidths within the frequency range of 8.2 to 110 GHz. In addition to the models listed below, models with 10, 20, 23 and 25 dB gain and other frequency bands are also available.

Handyscope TP450-250XM-W5
TP450-250XM-W5
The Handyscope TP450 is a power quality analyzer, connected via USB to the computer. The advanced measurement software delivered by default contains Quick Setups that allow to start mains power logging measurements without specialized instrument knowledge. With the 450 V input range, the Handyscope TP450 can be plugged directly in a (110 - 230 V) wall socket to measure the mains voltage. No additional attenuator is required. Logging mains voltage can be done at a high rate of 250 thousand measurements per second, with a resolution of 16 bit, which is equal to a 5½ digit voltmeter. The Handyscope TP450 is an accurate voltmeter, but one that performs 5000 measurements on each cycle of the mains voltage, while a standard voltmeter performs 3 measurements per second. Even with the very high measurement rate of the Handyscope TP450, the mains voltage can be measured continuously for weeks, and afterwards each period of the mains voltage can be analyzed thoroughly. Using this fast continuous measuring method, no voltage peak or dip is missed, even if it lasts just a msec. The maximum measuring duration of the mains voltage is only limited by the available hard disk space. Measuring one week takes approximately 0.69 GB disk space. During a measurement, also RMS value and frequency are logged. It is possible to measure various properties, like e.g. Minimum, Maximum, Peak to peak, Mean, Variance, Standard deviation.

Range-Doppler Target Generators
ATG9100
The ATG-9100 is an example of a laboratory-quality instrument that will simulate complex target motion. Microwave signals from the speed camera enter the instrument through an integrated antenna which is then downconverted and digitized. Target simulation data is added to the digitized signal to provide range and Doppler information. The modified digital data is then converted back to an IF and upconverted to the original microwave frequency of the speed camera and radiated back through the antenna. Since the ATG-9100 can be phase-locked to an external 10 MHz reference standard, this instrument is suitable for use as a calibration standard for speed cameras.
