Page 43 Calibration The HFS 9000 is shipped in a calibrated state, with the outputs deskewed to the front panel. Calibration settings are saved in a special non-volatile memory which is separate from any other memory in the instrument. Calibration adjusts the instrument to its internal voltage and timing references.
Page 44 If the test fails, the instrument may require service. When this happens, nominal values are put into calibration memory, and the instrument will be uncalibrated. However, the HFS 9000 will let you continue to operate the instrument after the initial warning that calibration memory has been reset.
Page 45: Channel Names
You have from 2 to 36 channels of output, depending on the type and number of cards you have installed in your HFS 9000 system. The HFS 9PG1 and HFS 9PG2 pulse generator cards provide two output channels, while the HFS 9DG1 and HFS 9DG2 data time generator cards provide four output channels.

Page 67: Operator Controls
GPIB Operator Controls One common application for the HFS 9000 is as one instrument in a suite of automated test equipment. In this environment, the controlling program may need to operate the HFS 9000 for extended periods without operator interven- tion.
Page 68 The operator then performs the necessary action, after which he or she presses the SRQ button. The program recognizes the button press, locks out the front panel, and continues to the next automated test. 2–32 HFS 9000 User Manual www.valuetronics.com...
Page 69 NOTE. The settings of the GPIB parameters are not changed when you reset or factory reset the HFS 9000 or when you recall settings. H Address lets you set the device address of the HFS 9000 (see Fig- ure 2–27).Valid device addresses are 0 through 30. Once the device address is set, all other devices will communicate with the HFS 9000 using its device address.

Page 71: Table 2-1: Output Voltage Limits
Levels You can set the voltage levels that the HFS 9000 uses for logical high and logical low. You can also limit the voltage levels that can be set with the normal level controls. Voltage level and level limit controls are provided for each channel individually.
Page 72 The controls for level limits are located in the Levels Menu (see Figure 2–29). Controls for voltage levels are also provided here. The associated display graphically shows the levels and limits for each channel. 2–36 HFS 9000 User Manual www.valuetronics.com...
Page 73 These can be set by knob or entered by keypad. As you change these values, the limit brackets in the associated display change to match. If limiting is on, moving a bracket into the voltage bar will cause the bar to shrink. 2–37 HFS 9000 User Manual www.valuetronics.com...
Page 74 Limiting also adjusts voltage levels values as you change the limits. Turning limiting off does not restore the channel voltage levels to their previous, unlimited, values. 2–38 HFS 9000 User Manual www.valuetronics.com...
Page 75: Phase Lock
You can synchronize and lock the HFS 9000 to an external timing source connected to the PHASE LOCK IN connector. This timing source then replaces the HFS 9000 internal clock. You can run the HFS 9000 at frequencies that are power-of-two harmonics or sub-harmonics of the phase lock signal. For example,...
Page 76 Figure 2–31 shows the Time Base menu with the detected phase lock frequency above the menu. NOTE. If the HFS 9000 cannot determine the phase lock frequency, an error message is displayed. This will happen if the phase lock signal is not stable and continuous, or if the phase lock signal is outside the allowed frequency range, or if the HFS 9000 needs calibrating.
Page 77 The frequencies you can use are limited to those within the frequency specifications of the HFS 9000. Triggering During Phase Lock Mode You can provide a triggering window while in phase lock mode.
Page 78 Phase Lock Phase Lock After Power on or Recall Phase lock is set to off whenever you power on the HFS 9000 or whenever you recall a setting. This is because a signal must be applied to the PHASE LOCK IN connector before phase lock is established.
Page 79 Power On When you power on the HFS 9000, it runs the self test diagnostics. Then it restores the instrument setting to the same way it was the last time it was powered off with the exception of the following two conditions: H All outputs remained turned off.
Page 80 Power On The configuration display shows the firmware version installed in the HFS 9000, and the cards that are installed. Each card also shows the card ID in quotes. You can change the card ID of any card through a programming interface by using the CAL:CID command.
Page 81: Pulse Generators
HFS 9PG1 and HFS 9PG2 cards, respectively. The HFS 9DG1 and HFS 9DG2 have four pulse generator channels. Thus, your HFS 9000 can have up to 36 pulse generator channels depending on the mainframe and number of cards installed.
Page 82: Voltage Levels
You can use the SELECT button to change High Level and Low Level into Amplitude and Offset. Amplitude is the voltage difference between the levels; offset is the voltage level assigned to the midpoint between the levels. 2–46 HFS 9000 User Manual www.valuetronics.com...

Page 97 Time Base The time base controls the timing of all channels of the HFS 9000. The time base defines times when the pulse channels will generate pulses. The time base can be externally triggered and phase locked to an external signal. The time base can provide an external trigger for other instruments.
Page 98 Time Base Burst Mode In burst mode, the HFS 9000 waits for a trigger event at the TRIGGER IN connector, a remote *TRG command, or a press of the MANUAL TRIGGER button. When a trigger event is detected, the HFS 9000 waits for approximately 130 ns (the startup delay) before generating pulses.
Page 99: Table 2-2: Logic State Of Outputs When Time Base Stopped
In Trig-Auto, the output is the same as with Auto mode but output does not begin until a trigger event is received. The HFS 9000 waits for a trigger event at the TRIGGER IN connector, a remote *TRG command, or a press of the MANUAL TRIGGER button.
Page 100: Manual Trigger
The HFS 9000 lets you set up conflicts but causes the conflicting menu items to blink. If you see a blinking menu item, look at other menu item(s) that are also blinking.
Page 101: Trigger Out
Time Base Trigger Out You can set the HFS 9000 to produce an external trigger signal at the TRIG- GER OUT connector. Use this output signal to trigger an external detection device such as an oscilloscope. The Time Base menu Out Period menu item lets you specify which pulse window in the burst will generate the output trigger.
Page 102 Time Base 2–66 HFS 9000 User Manual www.valuetronics.com...
Page 103 Trigger The time base of the HFS 9000 can be externally triggered and can be phase locked to an external signal. The HFS 9000 can also provide an external trigger signal for other instruments. Timing and Trigger Relationships The time base specifies when the pulse generator will create pulses relative to a trigger event detected at the TRIGGER IN connector.
Page 104 For complete information about using phase lock, see the Phase Lock section on page 2–39. Manual Trigger When the HFS 9000 is in Burst or Trig-Auto mode (set using the Time Base menu Mode item), you can use the MANUAL TRIGGER button to trigger the generation of pulse bursts.

Page 114: Command Syntax
Command Syntax You can control the HFS 9000 through the GPIB and RS-232-C interfaces using a large group of commands and queries. This section describes the syntax these commands and queries use, and the conventions the HFS 9000 uses to process them.
Page 115: Table 3-2: Command Message Elements
Command Syntax HFS 9000 to take a specific action. Queries cause the HFS 9000 to return information about its status. Most commands have both a set and query forms. The query form of the command is the same as the set form but with a question mark on the end. For example, the set command PGENA:CH1:HIGH has a query form PGENA:CH1:HIGH?.
Page 116: Table 3-3: Comparison Of Header On And Off Responses

Headers in Query You can control whether or not headers are returned by the HFS 9000 as part of Responses the query response. Use the HEADER command to control this feature. If header is on, command headers are returned as part of the query and the query response is formatted as a valid set command.
Page 117 Command Syntax Abbreviating Commands Many HFS 9000 commands can be abbreviated. These abbreviations are shown in capital letters for each command in the Commands section. For example, the command TBAS:PERiod can be entered simply as TBAS:PER or tbas:per. If you use the HEADER command to include command headers in query responses, you can further control whether the returned headers are abbreviated or are full-length.

Page 234: Status And Events
Status Registers The Standard Event Status Register (SESR) and the Status Byte Register (SBR) record certain types of events that may occur while the HFS 9000 is in use. These registers are defined by IEEE Standard 488.2-1987. Each bit in a Status Register records a particular type of event, such as an execution error or service request.
Page 235: Table 3-11: Sesr Bit Functions
*OPC command. The Status Byte Register (SBR). The SBR (see Figure 3–12 and Table 3–12) records whether output is available in the Output Queue, whether the HFS 9000 requests service, and whether the SESR has recorded any events.

Page 239 Whenever a command is issued resulting in a conflict, an event is generated on the EXE bit (bit 4). This is the equivalent of having blinking menu items when operating the HFS 9000 from the front panel. You can avoid generating this event if you concatenate commands so that the conflict is resolved when the command is completed.

Page 291 The performance verification procedure consists of the following steps, performed in the following order: 1. Perform the HFS 9000 internal self test that follows this list of steps. If the self test indicates problems, refer to the Maintenance section in the Service Manual to repair the instrument.
Page 292 The calibration procedure adjusts the instrument to its internal voltage and timing references and saves the settings in non-volatile memory. Calibrate the HFS 9000 at least every six months. The instrument does not need more frequent calibration unless it is reconfigured or used in an ambient temperature that differs by more than 5_ C from the temperature it was last calibrated in.
