33500 Series Firmware

The following improvement has been made in firmware release 5.02:

• Updated the ACCL version to improve memory leak.
   

For this release, update the Current Version Tab for all 33500B models as shown:

The following changes have been made in firmware release 5.00:

• Option IQP is now standard on the 33512B and 33522B. Upgrading these units to 5.0 without Option IQP previously installed will show the option as ‘Included’ in the System → Help → About window. Upgrading these units to 5.0 with Option IQP previously installed will continue to show ‘IQP’ as “Licensed”. There is no change in functionality. All other licensed options must be purchased. 
• Adds HTML5 emulation for additional instrument control options from the WebUI (user interface) for all 33500B series waveform generators. Selecting ‘Control Instrument’ on the WebUI enables selection of the control options.

The following improvements have been made in firmware release 4.00:
• Sweep functionality has been changed. The return-phase (if one is programmed) operates in the same type/spacing as sweep-phase.
• Sweep marker defect has been fixed. In previous revision, the sweep sync output did not work in “marker” mode if the sweep was a down-sweep.
• Sweep-type state recall defect has been fixed. The defect occurred because the front-panel instrument model differs from the SCPI/ remote programming model.
• Changes has been made in how limits are applied and when they are reported to the user. Minor improvements on the attempts to detect unreachable frequency/time combinations and respond by forcing the time settings to reachable values.
 

The following improvements have been made in firmware release 3.05:
• Log Sweep has been fixed to allow for low start and stop frequencies. Impossible log sweep combinations now detected and a “Settings Conflict” error is generated
• Linear Sweep has been fixed to allow for very small frequency spans (less than 0.1 Hz) with long sweep times (greater than 100 seconds). Impossible linear sweep combinations now detected and a “Settings Conflict” error is generated.
• Reduced brief transient voltage when power is turned off
• Faster power-up
• Proper knob operation when editing arbitrary waveforms from the front panel
• Corrects burst setup for triangle waveforms
• Allows more frequency resolution to be visible on the front panel in List Mode
• Allows more Phase Offset resolution on the front panel (increased from 0.1 degree to 0.001 degrees)

The following improvements have been made in firmware release 3.03:

• You can now use more than one character when setting the Cal Password
• You can now use more than one character while naming a file
• Improved behavior when performing a state recall of a BURST waveform
• Instrument now allows loading over 1000 arb segments into volatile memory
• Improved sweep behavior of an IQ arb
• Improved error checking when saving large arb files
• TRIG:COUNT:DEF now functions properly
• TIMER MIN/MAX/DEF now functions properly
• FM frequency functions properly when modulating arb waveforms
• Improved behavior of the Burst function while using Pulse waveforms
• Improved the behavior SYNC output during a state recall

The following improvements have been made in firmware release 2.09:

Modifications to front-panel and SCPI operation:

• You can now set phase in degrees, radians, or time. Simply change the default units from the Units menu (front panel) or with the UNIT:ANGLe command. You can also select the unit when setting the phase via the front panel or remote interface.
• New SCPI commands allow control over the appearance and content of the front panel display:

• You can disable front-panel key clicks via SYSTem:CLICk:STATe {OFF|ON} or the User Settings menu.
• Combine is no longer available when using a DC signal. You should use offset instead.
• The screensaver now dims the front panel display instead of turning it off.

Defects in existing instrument behavior have been corrected:

• Output trigger now functions correctly when the state is turned on or off.
• Frequency modulation of a square wave now allows the correct frequency deviation.
• Various minor defects for tracking mode have been fixed.
• The digit resolution is now correct when you use SCPI to set rms voltage.
• The *OPC? query now correctly determines the end of an NCYCLE burst of an arbitrary waveform.
• The signal distortion issue that occurred at various voltage ranges with an offset applied has been fixed.
• The instrument no longer displays ERR when resetting to defaults or during self-test.
• Amplitude modulation now functions properly with a depth set above 100%.
• When turning the output off, the signal no longer leaks to the BNC connectors.
• Copying a read-only file now produces a writable file.
• Trigger resolution is no longer truncated at five digits.
• Changing parameters on a bursted pulse with non-zero offset no longer produces a very short, unwanted pulse in Pulse Width mode. This pulse is still produced in Duty Cycle mode.

The following improvements have been made in firmware release 2.03:

• You can now easily synchronize arbitrary waveforms and sequences on two-channel instruments. Simply load arbitrary waveforms on both channels and use [Parameters] > More > Sync Arbs (front panel) or FUNCtion:ARBitrary:SYNChronize (SCPI). This stops both waveforms and simultaneously re-starts them at sample 1 and at whatever sample rates they happen to be set.
• In cases where the instrument is set to power up in the last (previous) configuration, a 10 Vpp ramp is now restored with the correct amplitude (was previously restored incorrectly to 8 Vpp).
• Instrument state files now store and recall the PRBS bit rate parameter correctly.
• The built-in instrument help now supports Russian help text. To configure this, press:
  [System] > System Setup > User Settings > Help Lang > More > Russian
• Instruments with static IP addresses no longer become unresponsive via the LAN.
• When restoring a state with power-on "last" or SCPI *RCL on a two-channel instrument, the phase relationship (if any) between the channels and the tracking mode (if any) are restored correctly.
• Updating firmware via the front panel and USB drive now requires unsecuring the instrument.
• On a two-channel instrument with GPIB, the front panel now displays the GPIB address correctly when the display is focused on channel 2.
• On 20 MHz models (33509B, 33510B, 33511B, 33512B), the maximum sample rate is now 160 MSa/s.
• An incorrect error message regarding modulating with a dual arbitrary waveform as the modulation shape has been removed.

To install firmware revision 1.14, your 33521A or 33522A must be connected to your local area network (LAN). If your instrument is not connected, see the 33500 Series User's Guide for instructions.

1. Power up the instrument on the LAN. Press the System > Help > About softkey sequence and record the instrument's LAN address.
2. Press System > Inst Setup > Calibrate, and if the title shows Calibration Locked, enter the security code with the knob and arrow keys and press Unlock Cal. The default calibration password is AT33520A. If the title does not show Calibration Locked, you do not need to take any particular action. You can also unlock calibration security by sending the command: CALibration:SECurity:STATe OFF,AT33520A.
3. Locate 3352xA Firmware Update Utility Type 2 in the Documents & Downloads section at the bottom of this page. Download and install this onto your computer.
4. Locate 3352xA Firmware Revision 1.14 in the Documents & Downloads section at the bottom of this page. Download this file to your computer and unzip it, making note of where you store the file.
5. Open the Firmware Update Utility on your computer:
   Start > All Programs > Keysight > Firmware Update Utility Type 2 > FirmwareUpdateUtilityType2.exe
6. Click Next.
7. Click Browse and browse to the firmware update file (Agt3352xA_rev_1_14.upd) that you saved in step 4. Highlight the file and select Open. It will take several seconds for the utility to read the file; wait until this message appears in the "Description" field:
   Keysight 33521A/33522A Rev 1.14
   NOTE: Front panel will go dark for
   about 30 seconds on first reboot.
8. Click Next.
9. Enter the IP address from Step 2 into the IP address field and click Update.
10. The utility verifies the connection to the LAN and the model number of the specified instrument. It then displays a confirmation dialog; click Yes to continue.
11. When a final information dialog summarizing the update will appears, press OK.
12. This update will take several minutes, and it will cause a reboot, during which the instrument front panel may go "dark" for about 30 seconds as new front panel firmware is installed. DO NOT cycle or interrupt power to the 3352xA during the update process.
13. Click OK when the pop-up message appears.
14. After this is completed, exit the update utility by pressing Cancel and then Yes.

The update process is now complete. You do not need to re-calibrate the instrument, but you may want to re-secure the instrument with the command CALibration:SECurity:STATe ON,AT33520A. Of course, you may choose a non-default password.
