PERFORMANCE TESTS

Introduction

The performance tests described in this section are designed to verify with a high degree of confi- dence that the unit is performing within the specifications.

The results of each test may be recorded on the test sheet at the end of this section.

[HARDKEYS]

The keypad consists of five groups of hardkeys. The ENTRY keys are used to enter numeric parameters which have been highlighted by a soft- key. The MENU keys select a menu of softkeys. Pressing a menu key will change the menu boxes which are displayed next to the softkeys. Each menu groups together similar parameters and functions. The CONTROL keys start and stop actual data acquisition, select the cursor and toggle the active display. These keys are not in a menu since they are used frequently and while dis- playing any menu. The SYSTEM keys print the screen to a printer and display help messages. Once again, these keys can be accessed from any menu. The AUTO keys are perform various auto functions and can be accessed from any menu.

Hardkeys are referenced in braces like [HELP].

<Softkeys>

The SR850 has a menu driven user interface. The 6 softkeys to the right of the video display have dif- ferent functions depending upon the information displayed in the menu boxes along the right edge of the screen. In general, the softkeys have two uses. The first is to toggle a feature on and off or to choose between settings. The second is to high- light a parameter which is then changed using the knob or numeric keypad. In both cases, the soft- keys affect the parameters which are displayed adjacent to them.

Softkeys are referenced in brackets like <Ref. Frequency>.

Knob

The knob is used to adjust parameters which have been highlighted using the softkeys. Most numeric entry fields may be adjusted using the knob. In addition, parameters such as sensitivity and time constant use the knob as well. In these cases, the knob function is selected by the softkeys. The [CURSOR] key, which can be pressed at any time, will set the knob function to scrolling the cursor.

Preset

Throughout this section, it will be necessary to preset the lock-in into a known default state. To do this, turn the power off. Turn the power back on while holding down the [←] (backspace) key. The unit will perform power up tests and then assume the default settings. Each test generally starts with a preset. This procedure will be referred to as {PRESET}.

Serial Number

If you need to contact Stanford Research Systems, please have the serial number of your unit available. The serial number is printed on a label affixed to the rear panel. The serial number is also displayed on the screen when the unit is powered on.

The serial number can also be displayed by pressing

[SYSTEM SETUP]

<Hardware Test > <More> <Screen Test>

Firmware Revision

The firmware revision code is displayed on the screen when the unit is powered on. The revision code is also displayed with the serial number in the Screen Test described above.
