Page 86: Multi-Interval Sweep
Note Changing the number of intervals will cause the HP 3324A to reset all sweep intervals to their default state, and all stores to be cleared, so don’t program any intervals until you are sure you have enough available.
Page 87 Each interval is programmed with its own start frequency, stop frequency, sweep time, marker frequency, and whether its swept either linearly or logarithmically. means A linear interval may be either up or down, this that the stop frequency may be higher or lower than the start frequency.
Page 88 The marker output is a TTL-compatible output. It is high at the start of each interval, and when the marker frequency is reached it goes low, where it remains until the end of the interval. 50 individually-programmmed intervals may be used in a customized sweep-sequence of upto 100 intervals.
Page 89 The sweep sequence (which can consist of one interval) can be swept either singularly or continuously. A single sweep means that the HP 3324A sweeps from the start frequency of the first interval in the programmed sequence to the stop frequency of the last interval in the sequence, and then remains there.
Page 90: Setting Up A Multi-Interval Sequence
This section will show how to set up a multi-interval Setting up a sweep sequence. Press lsweepl to show the Sweep menu. Multi-Interval To choose the multi-interval mode, put the cursor on Sequence “INTERVAL” and press (Select). A display similar to that in Figure 7-4 will be shown.
Page 91 When “INTERVAL” has been selected the current sweep sequence is shown. In the above example that is 1~3+6~2+9~4~9. This means that the sequence 1 3 4 5 6 2 3 4 5 6 7 8 9 4 9 is swept. m means “and then”, while (3) means “through”.
Page 92 To do this press the a key. You will then move onto some point in the list of start frequency, stop frequency, and so on. The position depends on where the cursor was when you last left and is shown by the parameter blinking.

Page 97: Multi-Marker Sweep
Multi-Marker The multi-marker sweep consists of only one linear interval, but upto 9 markers. The frequency for each Sweep marker is programmed separately. You can then activate the markers that you require. The marker pulsewidth is approximately 1 ms. For example consider having programmed the following interval.
Page 98 Figure 7-9. An Example Marker Sequence There is a minimal time difference of 1.5 ms between start- and marker-, marker- and marker-, and marker- and stop-frequencies. If a marker is too close to the start- or stop-frequency, it is not generated. If two markers are too close the second one (in time) is not generated.
Page 99: Setting Up A Multi-Marker Interval
A continuous sweep means that the HP 3324A sweeps from the start frequency of the interval to the stop frequency, and then remains there for a programmed time (retrace time), before starting again at the start frequency.
Page 100 In the sweep display, two values in the form “n of 9” are shown (in the above example “n” = “1”). “n” means the number of the marker whose frequency you will see if you put the cursor onto the marker frequency. The “9” is the number of markers that can be programmed and activated in the multi-marker interval.
Page 101 Having chosen the marker number you wish to program, you can move onto changing the frequency. To do this press (5J. You will then move onto the marker frequency. You can then change the frequency by either: Typing in a new value with the numeric keypad, and then pressing the appropriate unit key.
Page 102: Example
Example This example shows how to enter the sweep menu, and set up a single multi-marker sweep containing three markers. The start frequency will be 1 KHz, the stop frequency 10 KHz, and the sweep time 10 s. The markers will have the frequencies 3 KHz, 5 KHz and 7 KHz.
Page 103 The following display will be shown: SINGLE C O N T NRRKER-FREP SWEEP-TIME Figure 7-11. Marker Interval Example A single sweep has to be chosen now and the sweep started. Result Keystrokes T h e s w e e p s t a r t e d .

Page 127: Status Reporting
Status Reporting Introduction Another important feature of the III’ 3324A is that you can program it to interrupt the controller when certain status/error conditions are met. An 8-bit register, the Status Byte, contains the instrument’s status. In order for an interrupt to occur, it must be programmed via the Service Request Enable Mask.

Page 132: Forcing An Srq
Forcing an SRQ An SRQ is forced when one of the above bits in the Status Byte Register goes from “0-> 1” AND the corresponding Service Request Enable Mask bit has been set. Bits O-3 are never set if they are not enabled via the SRQ-mask command.
Page 133: Service Request Enable
Service Request The SRQ mask can be set to mask bits O-3 of the Status Register. To set the mask first determine which Enable conditions you want to interrupt the controller, for example sweep started, sweep stopped and so on. Determine the decimal number (1-16) corresponding to those conditions.
Page 134: Example 1
Example 1 The following example shows how to set the SRQ mask, so that if a “0 + 1” transition of the Sweep Started or System Failure bit occurs, an interrupt is sent. S y s t e m Sweep A l w a y s S y s t e m Sweep Sweep...

Page 237: Hp-Ib Overview
Introduction This appendix gives an overview of the Hewlett-Packard Interface Bus (HP-IB). Description of the The HP-IB is a bus structure that links the HP 3324A to desktop computers, minicomputers, and other HP-IB HP-IB controlled instruments to form automated measurement systems.
Page 238 Every participating device must be able to perform at least one of the following roles; talker, listener or controller. The HP 3324A can be either a talker or a listener. The full flexibility and power of the HP-IB is realized when a controller is added to the system.
Page 239: Capabilities Of The Hp-Ib
Address Capability Primary addresses: 31 talk, 31 listen; secondary (2-byte) addresses: 961 talk, 961 listen. 1 talker and 14 listeners, maximum, at one time. The HP 3324A has only primary address capability. Table D-l lists the talk and listen HP-IB addresses.

This line is used by the active controller to define how information on the data lines should be interpreted by other devices on the bus. When ATN is low (true) the HP-IB is in the command and the data lines should be interpreted as bus mode...
Page 241: Srq . Service Request
The HP 3324A responds to a serial poll by putting its status byte on the data lines (see Chapter 10 Status and Event Reporting).
Page 242 Talk/Listen Each HP-IB device has at least one talk and one listen address unless the device is either totally transparent or Addresses is a talk-only or listen-only device. Device addresses are used by the active controller in the command mode (ATN true) to specify the talker (via a talk address) and the listener(s) ( via listen addresses).
