  • HP 70902A IF Section Resolution Bandwidth

    $225.00

    This module is a component of several Hewlett Packard spectrum analyzers based on the 70K series Modular Measurement System (MMS). It is easiest to quote the Agilent website for an overview:

    “The Agilent 70902A provides narrow resolution bandwidths, from 10 Hz to 300 kHz. This intermediate frequency (IF) section provides signal processing elements required for spectrum analyzers and lightwave signal analyzers. The Agilent 70902A maximizes measurement speed using 10% incremental bandwidths. Wide bandwidths offer the most speed, whereas narrow bandwidths offer more resolution and sensitivity. The 10% incremental bandwidth steps offer you the best choice of bandwidth sizes. The bandwidths can also be changed in a 1, 3, 10 sequence. Calibrated logging amplifiers provide superb amplitude accuracy for the analyzers. The 3 MHz IF output on the Agilent 70902A allows connection to other instruments such as demodulators, digitizers, and oscilloscopes..

    HP / Agilent 70902A Features
    • Provides narrow resolution bandwidths from 10 Hz to 300 kHz
    • Bandwidths in 10% increments (except 3 kHz to 10 kHz)
    • Logging amplifier and detector
    • 3 MHz IF output allows connection to other instruments”

    Also, from the HP Installation Manual:

    “The HP 70902A IF Section is a 1/8-width module, providing a resolution bandwidth of 10 Hz to 300kHz, designed for use in HP 70000 Modular Measurement Systems. The module processes a 21.4MHz signal from a spectrum analyzer RF section or external mixer interface module. A detected video signal is produced and routed to the video processor in the local oscillator. The module contains resolution bandwidth filters, log amplifiers, detection circuitry, and video filters. The HP 70902A can be used with an HP 70903A in a single system to provide resolution bandwidths of 10 Hz to 3 MHz.

    The HP 70902A is a slave module and as such is controlled by the system master (for example, the HP 70900A(B) Local Oscillator).”

    The module is in exceptional cosmetic condition. It was tested prior to being placed in inventory in a complete system and found to perform properly without errors.

  • Wild Drawing Tube after Treffenberg, Modified for

    $375.00

    This Wild Drawing Tube has been tested and is not working properly – selling as parts.

    Here is a very rare item. It is a drawing tube assembly (after Treffenberg) initially made for the Wild M20 compound microscope, however this tube has an interesting modification. The mounting flange for the tube fits the tube fittings on the Zeiss ‘Grayline’ instruments. The receptacle for the viewing tube has not been altered – in other words it requires a Wild style viewing tube. The modification appears to have been done at the Heerbrugg factory since the entire central prism holder has been machined with the Zeiss flange accommodation in mind. It is not possible to simply remove the Zeiss flange and replace it with the Wild flange.

    The drawing tube is interposed between the viewing head and the stand. A beam-splitter in the intervening disk superimposes an image of the desktop adjacent to the microscope onto the microscope image. The magnification ratio between the microscope image and the desktop image is regulated by a sliding sleeve (with the +V and V- markings). The desktop image is focused with the chrome knurled ring on the distal end of the tube. There is a swing-out filter holder in which a neutral density filter may be placed to assist in balancing the illumination (neutral density filters are not included).

    The tube has a magnification factor of 1.25x. The optics in the tube are perfect – no delamination and no blemishes in the surface. Cosmetically the tube is in excellent condition showing some minor signs of use – most notably in the uneven finish of the distal prism housing (see last photo).

    Drawing tubes remain an important device in the microscopists arsenal – often they are very helpful to make drawings of highly complex subjects in which the details of interest are otherwise obscured. They are also very useful during video microscopy if you wish to superimpose some sort of readout on the image while recording some dynamic event.

  • Cryogenic Water Vapor Pump Liquid Nitrogen

    $1,150.00

    This is an American Cryo Tech – Cryogenic Sorption/Water Vapor Pump – Liquid Nitrogen Cooled

    The vacuum port connection is a 6 inch Conflat.

    The sorption pump is a cyclic pump and its cycle has 3 phases: sorption, desorption and regeneration.

    1. In the sorption phase the pump is actually used to create a vacuum. This is achieved by cooling the pump body to low temperatures, typically by immersing it in a Dewar flask filled with liquid nitrogen. Gases will now either condense or be adsorbed by the large surface of the molecular sieve.
    2. In the desorption phase the pump is allowed warm up to room temperature and the gases escape through the pressure relief valve or other opening to the atmosphere. If the pump has been used to pump toxic, flammable or other dangerous gasses one has to be careful to vent safely into the atmosphere as all gases pumped during the sorption phase will be released during the desorption phase.
    3. In the regeneration phase the pump body is heated to 300 °C to drive off water vapor that does not desorb at room temperature and accumulates in the molecular sieve. It takes typically 2 hours to fully regenerate a pump.

    The pump can be used in a cycle of sorption and desorption until it loses too much efficiency and is regenerated or in a cycle where sorption and desorption are always followed by regeneration.

    This unit came from a working environment but has not been tested.
