½Label disks as follows:
V3.52 DISK 1
V3.52 DISK 2
V3.52 DISK 3
V3.52 DISK 4
V3.52 DISK 5
½Create a temporary directory on your PC (e.g. ZVRTEMP on C:\). For this you require about
3 Mbytes of free memory on your hard disk.
½Copy file disk1.bin to this temporary directory.
½Rename file disk1.bin to disk1.exe.

ZVx Firmware Version 3.52
1112.8050.52 3 E-17
½Execute disk1.exe, e.g. by using the following command sequence for Windows95/NT:
<CTRL><ESC> - RUN –C:\ ZVRTEMP \DISK1 - <ENTER> (English version) or
<CTRL><ESC> - AUSFÜHREN –C:\ ZVRTEMP \DISK1 - <ENTER> (German version).
The files are extracted.
½Delete file disk1.exe in the temporary directory.
The temporary directory should contain the following files:
_inst32i.ex_ _isdel.exe _setup.dll _sys1.cab _user1.cab
data.tag data1.cab lang.dat layout.bin os.dat
readme.txt setup.exe setup.ini setup.ins setup.lid
½Copy all files to update disk 1 (V3.52 DISK 1).
Check if all files are on the disk with their correct names. In particular, the underscores ("_" as in
"_inst32iex_") are essential for a successful update.
½The contents of the other 4 disks are already in the format needed for the update. Files
data2.cab,..., data5.cab must be copied to the corresponding disks DISK2, ..., DISK5.
The disks are now ready, and you can continue with section 2 "If you have received a firmware
update kit on a disk ...".
Notes: If any error messages are output during creation of a disk, the installation process for the
disk in question must be repeated. Before re-creating the disk, check if the write
protection of the disk has been removed.
File disk_d.bin contains this document in pdf format. To unpack the document proceed as follows:
½Copy disk_d.bin to the temporary directory.
½Rename the file to disk_d.exe.

Improvements
•When reading and writing system error correction data and level correction data in the REAL64
format, an error message is output.
Affected IEC/IEEE bus commands:
SENSe[1..4]:CORRection:DATA
SENSe[1..4]:CORRection:POWer:DATA
SOURce[1..4]:POWer:CORRection:DATA
•If a waveguide calibration (WAVEGUIDE = ON) is performed via IEC/IEEE bus with a CUTOFF
FREQUENCY that is higher than the START FREQUENCY, an error message is now output
because this action is not permitted.
•Omission of unnecessary level calibration interpolation (improves performance especially during
operation via the IEC/IEEE bus).
•The CALC:MARK:FUNC:RES? IEC/IEEE bus query now yields 10 significant marker points
(previously only 6).
•Improvement of signal quality of R&S SMR generators (SMR20/27/30/40/50/60,
SMR20/27/30/40/50/60B11) in TTL mode.
(This requires an SMR firmware version ≥1.26.)
•Generators currently not used are switched to RF OFF. This prevents erroneous measurements
and avoids disconnecting any cables.
Examples:
- During power calibration of the internal generator, any external generators connected to the
instrument and set to REMOTE are switched to RF OFF.
- This applies analogously to the calibration of an external generator. In this case, the internal ge-
nerator (and, if available, a second external generator connected and set to REMOTE) is switched
to RF OFF.
- When a COMP/SOI/TOI, arbitrary or mixer measurement is switched off, the external generators
used in the measurement are set to RF OFF.
Modifications
•New softkeys or softkeys shifted to another position in menu CAL →CAL KITS:
- Softkey USER CONN NAME now at position 9 of right side menu
- Softkey USER CONN IMPEDANCE now at position 10 of right side menu
- New softkey UNINSTALL KITS at position 10 of main menu
- New softkey WAVEGUIDE at position 6 of right side menu
- New softkey CUTOFF FREQUENCY at position 7 of right side menu

ZVx Firmware Version 3.52
1112.8050.52 7 E-17
3 Bug Fixes
•In the ACTIVE xx STANDARDS table, the entries for the OPEN standards are again available when
a calibration is performed.
•System error correction data sets generated with a version <3.50 can now be recalled again
(RECALL).
•The power correction function has been improved:
- External power calibration is reliably activated with COMP/SOI/TOI measurements.
- An existing power calibration can be used again in power sweeps and in time sweeps.
•The normal user (logged on under the name "INSTRUMENT") has write access again to the
directory AUTOKAL, so the AutoCal function works again.
•Commanding the OFFSET SHORT standards
(SENSe[1..4]:CORRection:COLLect:ACQuire:OSHORT1 or OSHORT2) in case of waveguide
calibration (WAVEGUIDE = ON) is possible again.
•Errors were corrected in the following SCPI commands:
- SENS:FUNC?
- SOURce:POWer:[LEVel]:[IMMediate]:CAMPlitude
•Softkeys that were not visible are now available again:
- Menu MEAS →USER DEF’D S-PARAMS: softkeys USER DEF’D S-PARAMS and USER DEF ACTIVE
- Menu CAL →START NEW CAL →FULL ONE PORT →BOTH PORTS: softkey 2.92 mm FEMALE
- Menu MEAS →WAVE QANTITY: softkey DRIVE PORT

4 Extensions to Operating Manual
Characteristics of Calibration Standards (Re section 2.15.1.3)
The MODIFY CAL KIT softkey opens a menu for the management of calibration kits for the individual
connector families.
Exact knowledge of the calibration standards is a prerequisite for a accurate system-error calibration.
More precisely, the calibration is based on the knowledge of those S-parameters of the standards which
are assumed to be known for the applied calibration method. These S-parameters are derived from
physical models which contain one or more parameters (such as the electrical length) depending on the
type of standard.
In addition to these physical parameters, there are three description fields for each standard listing the
assignment of the standard and further information for the user.
1. Standard type: The type depends on the kind of standard (e.g. open circuit, short circuit, through-
connection) and the sex of the connectors. Example: THROUGH (MF) denotes a through-
connection with a plug at one and a socket at the other port. The standard type determines the
physical description model and therefore the parameters which can be edited. Up to four individual
standards with different parameters can be defined for one standard type. Only one of them can be
selected (active) at one time.
2. Calibration kit (KIT): A calibration kit is an assembly of real, physical calibration standards.
Calibration kits are supplied by Rohde & Schwarz as an accessory for network analyzers. The
parameters of the standards in a calibration kit are stored on a floppy disk which can be read in via
the INSTALL NEW KIT softkey. Kits for coaxial connector families usually do not contain all possible
standard types of these families but only a subset comprising the types which are most frequently
used in coaxial technology. Calibration kits can be user-defined as well. Using the ACTIVATE KIT
softkey, the standards of a calibration kit can be selected altogether by just one keystroke.
3. Serial number (SERIAL #): All standards of a calibration kit are factory-labelled with the same serial
number so they can be assigned unambiguously to this kit. The serial number helps to avoid
confusion between standards of the same type from different calibration kits which might have
different physical parameters.

Selecting the connector families
After pressing the CAL KITS softkey, the ACTIVE XX STANDARDS selection table is
displayed, where XX denotes the connector family selected. By default, the
connector family of the test set ports is selected. The table gives an overview of the
active standards of the connector family:
•The STANDARD TYPE column lists all standard types which are required for the
calibration procedures of the respective type of instrument.
•The KIT column indicates to which calibration kit the currently selected physical
standard belongs. By default, for standard types contained in the calibration kits
offered by Rohde & Schwarz, the designation of the corresponding kit is also
displayed. Although typical parameter values are pre-defined for these standards,
the individual parameters for each calibration kit, which are supplied on a floppy,
should be read in for the sake of maximum accuracy (see INSTALL NEW KIT
softkey). The predefined standards without calibration kit assignment are
assumed to be ideal.

Firmware Version 3.52 ZVx
1112.8050.52 10 E-17
The cursor can be used to select the standard type the softkeys MODIFY
STANDARDS and VIEW ACTIVE STD refer to.
For polarized connector families, three types exist for each two-port standard,
namely male/male (MM), female/female (FF), and male/female (MF). One-port
standards are provided as male (M) and female (F). For non-polarized connectors,
such as PC 7, all standards are contained only once in the table.
If a calibration method requires to measure two standards with the same polarity
simultaneously, their characteristics are assumed to be identical. This applies, e.g.,
to the TOM-X calibration method if the OPEN BOTH PORTS measurement is
performed.
The following types of standards are provided for the various types of network analyzers. Due to the
restricted calibration facilities of the ZVRE, ZVCE and ZVRL compared to the ZVR, ZVC, ZVK and ZVM,
a reduced set of standards is required only.

SEXLESS
USR CONN 1 The SEXLESS USR CONN 1 softkey displays the table ACTIVE USER CONN 1
STANDARDS. The connector family SEXLESS USR CONN 1 which can be user-
defined is not polarized (similar to PC 7) and particularly suited for non-coaxial cable
systems such as microstrip.
The two user-defined connector families SEXLESS USR CONN 1 and USR CONN 2
can also be used for waveguide calibration (refer to WAVEGUIDE softkey
description). As waveguides are as a rule not polarized, SEXLESS USR CONN 1 is
to be preferred to USR CONN 2.
The name of this connector family (USER CONN 1 by default) can be modified via
the USER CONN NAME softkey.
USR CONN 2 The USR CONN 2 softkey displays the table ACTIVE USER CONN 2 STANDARDS.
Unlike SEXLESS USR CONN 1, this user-defined connector family is polarized and
therefore suited for the coaxial connectors that are not pre-defined in the
CONNECTOR TYPE menu. The connector family USR CONN 2 can also be used
for waveguide calibration.
The name of this connector family (USER CONN 2 by default) can be modified via
the USER CONN NAME softkey.
