Page 24: Introducing The Gould Ultima 500
Ultima 500 DSO Introducing the Gould Ultima 500 Congratulations on your purchase of the Ultima 500, the first in a family of Gould Workstation DSO’s. Combining the acquisition power of a high performance four-channel DSO with the flexibility and features of a PC, Ultima 500’s unique capability simplifies data handling by effortlessly moving from capture to report in one compact unit.
Page 25 Ultima 500 DSO Chapter 3: Introduction ProView Analysis and Report Software – Accepts data directly from Ultima, providing lightning fast display and processing of data. A formula database with over 100 math functions defines custom calculations. ProView is automatically updated every time Ultima acquires new data, or when manually commanded with a one-button control.

Page 29: Auto Setup
Ultima 500 DSO Chapter 4: Using the Front Panel Controls Auto Setup Pressing this button opens a menu to the left which requests confirmation. This confirmation prevents activating the Auto Setup feature in error. Auto Setup interrogates all (four) channel inputs and sets the amplitude scale for appropriate viewing.
Page 30 Chapter 4: Using the Front Panel Controls Ultima 500 DSO Page 1 / Page 2 The Ultima has two modes of operation which are displayed in Page 1 and Page 2. This control toggles the display between Page 1 and Page 2. Toggling between pages does not affect the setup of either page.
Page 31: Cursor Controls
Ultima 500 DSO Chapter 4: Using the Front Panel Controls Cursor Controls The front panel Cursor 1 and Cursor 2 controls adjust the position of the cursors seen on the display. Vertical cursors measure time and Y value at the cursor, Horizontal cursors measure amplitudes manually and crosshair cursors measure both time and amplitude.
Page 32: Trace Select
Chapter 4: Using the Front Panel Controls Ultima 500 DSO Trace Select Trace Select toggles the selection of the active trace among the (displayed) traces. The Cursor Panel at the bottom of the screen indicates the selected trace. Trace Select also controls which trace the Snapshot Measurements are performed upon.
Page 33 Ultima 500 DSO Chapter 4: Using the Front Panel Controls Equivalent Time Sampling (ETS) The fastest timebase ranges are achieved when using Equivalent Time Sampling. This is a technique whereby a complete trace is built up by sampling a number of acquisitions at various times relative to the trigger point.
Page 34 Chapter 4: Using the Front Panel Controls Ultima 500 DSO Memory Length & Sample Rate The Ultima can display up to 500 columns per horizontal sweep. When the memory length is 500 samples, there is one sample per column. When memory lengths are greater than 500, video compression is used.
Page 35 Ultima 500 DSO Chapter 4: Using the Front Panel Controls Avoiding Aliasing with Glitch Detection Glitch Detect feature exposes aliases. With dot join on, this usually results in a filled-in wave envelope being seen on the screen, indicating a high frequency, as shown below.
Page 36 Chapter 4: Using the Front Panel Controls Ultima 500 DSO External Clock To use an external clock as the timebase, move the Time/Div control counterclockwise until EXT appears on the display. The external clock TTL input is on the rear panel in a “D” type connector.

Page 38 Chapter 4: Using the Front Panel Controls Ultima 500 DSO X Zoom Factor Pressing the Time/div control turns this knob into the X Zoom Factor control. The Zoom Bar across the top of the display grid and the vertical line then brighten up, signifying that the Ultima is in Zoom Set mode.
Page 39 Ultima 500 DSO Chapter 4: Using the Front Panel Controls Position – X Zoom When the Ultima is in Zoom Set mode, this control moves the position of the Zoom Bar, and thus the region of the main trace to be zoomed, from the beginning of the main trace to the end.
Page 40: Vertical Controls
Chapter 4: Using the Front Panel Controls Ultima 500 DSO Vertical Controls The primary channel (input) controls are front panel rotary style and push button. They are individual for each channel to facilitate ease of use. Channel Scale The scaling for each input is adjusted in 1-2-5 steps using the Scale knob.
Page 41 Ultima 500 DSO Chapter 4: Using the Front Panel Controls Channel Position The Position control shifts the baseline of the respective trace up or down. Turn the control clockwise to shift the trace up and counterclockwise to shift the trace down. The control applies acceleration if it is operated quickly and continuously in one direction.
Page 42 Chapter 4: Using the Front Panel Controls Ultima 500 DSO Channel Coupling AC-DC-GND The coupling control cycles the respective input between AC, DC and Ground. DC is the most generally applicable coupling so Auto Setup sets this control to DC when possible.

Page 64: Resolution
The 10-bit mode requires fewer triggered events to obtain a complete capture and therefore completes an acquisition with increased speed. For more information on this high resolution mode, see The Gould High Resolution System. 6-14 Version 2.3...
Page 65 (MAIN and ZOOM display) resolution (MAIN and ZOOM display) The Gould method of acquiring high resolution signals involves injecting a dither signal in series with the input and then over-sampling. The dither signal is extracted after the ADC conversion to digital with special DSPs. The dither signal effectively offsets the signal relative to the ADC levels.
Page 66: Memory Length
Chapter 6: Using the Main Menus Ultima 500 DSO Memory Length Both the memory length and sample rate determines the total time your system will acquire data. Memory Length X 1/(Sample Rate) = Total Acquisition Time It is often best to start with a high sample rate and a large memory length to obtain the highest resolution on the entire data set to be collected.
Page 67 Ultima 500 DSO Chapter 6: Using the Main Menus Arbitrary Memory Select the number of points to capture using the Cursor 2 control or use the mouse to move the slider. Enter the number from the keyboard or press the Memory Length button again to select the numeric entry from the bezel buttons.
Page 68 Chapter 6: Using the Main Menus Ultima 500 DSO Multi Shot The Multi Shot function offers the ability to segment the acquisition memory allowing multiple acquisitions packaged into one data set. When Multi Shot is selected the memory mode is automatically switched to Arbitrary to accommodate the number of segments with the preset length.
Page 69: Fast Modes
Ultima 500 DSO Chapter 6: Using the Main Menus Fast Modes Fast Modes are used to tailor the acquisition engine to various high-speed data capture applications. Select the mode using the Cursor 2 control or mouse click. ETS - Repetitive signals only - the fastest timebase ranges are achieved when using ETS (Equivalent Time Sampling).
Page 70: Glitch Detect
Chapter 6: Using the Main Menus Ultima 500 DSO Glitch Detect Glitch Detect Turns on or off the feature. Use the Cursor 2 control or mouse click to make the selection. Any sample rates less than the fastest (500 MS/s) increase the chance to miss a fast transient.
