1995_gemini_PURE | The requirements to have instruments operated as single units imply that several user stations will be active at the same time on the Gemini 8m Telescopes. On these user stations, different kinds of users may be working at the same time with the Gemini 8m Telescopes software. Independently of the location of users at the telescope site, they shall be able to access (according to their privileges) any part of the whole setup with a simple logon and coniguration operation. In other words. any subsection of the whole Gemini 8m Telescopes system should be accessible and controllable from any single point (but of course with protection ensuring security and safety). A particularly simple case of multi-use of the system is multi-point monitoring. By this it is meant that, while some (active) user is in control of the Gemini 8m Telescopes, someone else can follow what they are doing by monitoring all the relevant data from telescope and instruments. This will typically be needed by the operation supervisor. All other users wishing to monitor Gemini 8m Telescopes operations have to go through the procedures set up by Operations and get permission to do so. The multi-point monitoring mode might also be important when certain dificult or rare problems occur, when expert advice is needed and can only be obtained from colleagues situated remotely. Multi-point monitoring allows them to follow directly the results of tests performed and investigate how the system is working (e.g. by selecting different display pages with the up-to-date status information on different parts of the system). Multi-point monitoring also allows a local observer to be monitored and advised by a remote supervisor. Monitoring shall exist both in the form of automatic displays of status information at different locations, and in the form of explicit access to the required status information from any point. Monitoring shall not affect the performance of ongoing observations. |

spacebert_ecss | The test procedures shall be as follows: 1. Turn on the measurement equipment and wait until it is stabilized. 2.

NOTE A power amplifier can be necessary at 1 kHz. (b) Apply through the current probe a DC-current equivalent to the EUT supply current. NOTE 1 A DC current is applied for verifying that the current probe will not be saturated by the EUT DC supply current. NOTE 2 This DC current is applied through the LISN for applying the same impedance through the probe as with the EUT. (c) Verify the AC current level as measured with the probe by comparison with voltage across the 1 W resistor at 1 kHz and the 10 W resistor at 100 kHz; also, verify that the current waveform is sinusoidal. (d) Scan the measurement receiver for each frequency in the same manner as a normal data scan. Verify that the data-recording device indicates a level within ±3 dB of the injected level. (e) If readings are obtained which deviate by more than ±3 dB, locate the source of the error and correct the deficiency prior to proceeding with the testing. 3. Test the EUT by determining the conducted emissions from the EUT input power leads, hot line and return, and measure the conducted emission separately on each power lead, as follows: (a) Turn on the EUT and wait for its stabilization. (b) Select a lead for testing and clamp the current probe into position. (c) Scan the measurement receiver over the frequency range, using the bandwidths and minimum measurement times specified in Table 5-2, clause 5.2.9.1. (d) Repeat 5.4.2.4a.3(b) and 5.4.2.4a.3(c) for each power lead. |

spacebert_ecss | The test equipment shall be as follows: 1. DC high voltage supply or an ESD generator as specified in IEC 61000-4-2 (Edition 1.2).

The discharge primary circuit is constituted of: (a) 6 kV spark gap, NOTE 1 An air spark gap or an overvoltage suppressor in a sealed pressurized envelop can be used. NOTE 2 An air spark gap is less stable and has longer rise time. (b) 50 pF capacitance, high-voltage capacitor with inductance less than 20 nH, (c) 47 W damping resistor (high voltage specification), NOTE The value can be adjusted at critical damping depending on value of capacitance C and self-inductance of the discharge circuit; (d) 10 kW resistors (high voltage specification). NOTE Choke resistors prevent high-frequency components of discharge from flowing in uncontrolled paths so the discharge parameters are not dependent on length and position of high-voltage source wires. 3. Monitoring devices: (a) Two current probes, 100 A peak capability and more than 100 MHz bandwidth, (b) One high-voltage probe, 10 kV range, 1 MHz bandwidth, NOTE If the probe input impedance is not high enough, it can prevent gap arcing by lowering the available voltage.
