Consent Agenda

Electronic Test Equipment Purchase

I propose we hold a popular vote to approve the purchase of the electronics test equipment described in this section from Cate Grey for $750, paid from our tool fund. This amount is 10% below the estimated cost for the same tools bought new.

The equipment was very lightly used and was carefully tested by Pete Soper. Here are his notes and list prices for new equipment of the same type (which totals $833):

  1. EZ OS-5020 Dual trace 20mhz Oscilloscope with one HP 2040 1X/10X probe. This is a modest 'scope but seems to work fine and should meet the needs of Splatspace users for casual use. The scope costs $395 currently and the probe costs $20. (If this equipment is obtained for Splatspace a second probe should be ordered to enable the 2nd channel, along with some spring-hook clips for more convenient connections in some contexts).
    1. Scope: http://www.amazon.com/EZ-Digital-OS-5020-Oscilloscope-Triggering/dp/B00G5M8TQO/ref=sr_1_12?ie=UTF8&qid=1391979697&sr=8-12&keywords=dual+trace+oscilloscope
    2. Probe: http://www.ebay.com/itm/OSCILLOSCOPE-PROBE-KIT-HP-2040-/230675273012
  2. Webtronics/Mastech DC Power Supply. This is a beautiful variable voltage power supply that offers both constant voltage (i.e. the usual) and CONSTANT CURRENT. The latter feature can be extremely useful for some situations. The supply delivers 0-30 volts at 0-3 amperes between it's + and - terminals (NOT from ground: this supply appears to be fully isolated). There are both current and volt meters. This supply currently costs $160.

  3. Mastech 2mhz signal generator. This is also a very useful piece of equipment that would fill a hole on the current Splatspace work bench. It generates sine, triangle and square waves and has a built in digital counter. A digital meter shows the actual frequency output/counted. It currently costs $108

  4. MFJ MFG-4035MV High current regulated power supply. This supply is very flexible, having binding posts, a "cigar lighter socket" and speaker-type spring clip connections as well as both an ammeter and a volt meter. It's good for 35 amperes but it will reliably put out quite low voltages at high current. Current price is $150.
  5. Two antistatic wrist straps and a hex crimper for connectors like TNCs.
