R&S FSH-K1 Enabling Remote Control Option R&S FSH-K1
Enabling Remote Control Option R&S FSH-K1
The R&S FSH spectrum analyzer can be fitted with the Remote Control Option R&S FSH-K1, which is
enabled by entering a key code. The key code is based on the unique serial number of the instrument.
To retrofit an option, enable it with a key code.
Operation
Press the GENERAL key.
Use the Rotary knob or the Cursor keys to select the OPTIONS... menu item and confirm the entry
with the ENTER key.
Enter the key code (ten-digit number) for the option with the decimal keys and confirm with the ENTER
key.
If the correct key code is entered, the R&S FSH displays "Remote Control enabled".
If an invalid key code is entered, the R&S FSH displays "Option key error".
The correct key code can then be entered.

Connecting PCs R&S FSH-K1
Connecting PCs
The R&S FSH can be remote controlled by a PC or Laptop equipped with an USB interface or a RS232
interface.
RS232 optical interface
The RS232 optical interface is used for connecting a PC or Laptop. The interface connector is located
at the right-hand side of the R&S FSH, it can be accessed by folding out the support.
The USB Optical Interface Cable R&S FSH-Z37 (supplied with the R&S FSH) or the RS232 Optical
Interface Cable R&S FSH-Z34 are used to make the connection. The optical connection prevents
spurious measurements being caused by interference from these devices.
Fold out the support at the rear of the
R&S FSH.
Connect the optical connector of the
RS-232 cable to the optical interface
on the right-hand side of the
R&S FSH.
Connect the USB connector of the
cable to the USB connector of the PC
(R&S FSH-Z37) or the 9-pin D-Sub
connector of the cable to the RS-232
connector of the PC (R&S FSH-Z34).
For the USB cable R&S FSH-Z37:
Install the USB driver supplied on the
R&S FSH CD-ROM.
Installation of the driver for the USB optical cable (R&S FSH-Z37)
The USB driver available on the R&S FSH CD-ROM emulates a serial COM port on the PC. In order to
install the driver on a PC equiped with Windows XP or Windows 2000 please proceed as follows:
Connect the optical USB cable to the PC. The hardware installation wizzard will pop up and state
that it has found a USB to serial bridge.
Insert the R&S FSH CD-ROM.
Select “automatic software installation” and press “Next”. The installation wizzard will automatically
search for the necessary driver and install it.
In case that the wizzard does not find the driver files you will be prompted for manual entry of the
corresponding path. The driver is located on the CD-ROM in folder “\drivers\USB”.
Press “Finish” in order to finalize the installation. The USB cable is now ready for use.
Serial Port Configuration
The serial interface configuration on the PC should be set to
8 data bits, 1 stop bit, no parity
The baud rate can be configured via the Setup menu on the R&S FSH or the SET BAUD command.
The baud rates can be 9.600, 19.200, 38.400, 57.600 or 115.200 Baud. The default baud rate is 19.200
Baud

Notational Conventions
The following section describes the notational conventions as they are used throughout this document.

“...” Characters between “ “ are taken as they are, but the “ “ are excluded
[...] Specifies an optional element
{...} Specifies an element that may be repeated.

Starting Remote Control Operation
On power-on, the R&S FSH is always in the manual operation state (“LOCAL” state) and can be
operated via the front panel.
If the R&S FSH receives a remote command the
instrument remains in local state. It is switched to
remote state as soon as it receives the command
“REMOTE” from the PC.
In remote state the front panel access is disabled.
The R&S FSH can be switched back to local state
by sending the LOCAL command.
1157.3564.12 3 E-10
Device Messages R&S FSH-K1
Device Messages
The remote control command set of the R&S FSH can be grouped into three categories:
• SET commands
SET commands are used to program parameters of the instrument like
center frequency, span, etc.
• GET commands
GET commands are used to query current settings and data from the instrument like
center frequency, marker, trace data, etc.
• CMD commands
CMD commands are used to initiate an action or a state transition in the instrument like
marker-to-peak, preset, remote state, etc.
Acknowledge Response <ack>
After receiving a SET, GET or CMD command the R&S FSH responds with an “acknowledge”
message. The acknowledge message consists of an ASCII digit (“0” for no error) followed by a Carriage
Return <cr>. The response message indicates if the command or parameter is valid.
A second acknowledge response is generated after the command parameter.
<ack> response:
“0” No Error.
“1” Syntax Error. This response is generated when the command sent to the instrument is not
known or when the timeout on data reception expired. It is also generated, when the
parameter or value for the command are in the wrong data format.
“2” Execution Error. The command sent is not allowed in the current measurement mode.
“3” Dataset Storage Full. This response is generated when the dataset storage is full.
“4” Not Allowed. In the current state of the R&S FSH setting this parameter or value is not
allowed.
“5” Out Of Range. The parameter value is out of range and cannot be programmed.
Timeout
To prevent any lockups in the communication between PC and instrument the data transfer via the
serial interface is monitored by the R&S FSH. There is a timeout time of 60 seconds on every byte
received by the instrument. When the time between 2 bytes in a command or parameter send exceeds
60 seconds the R&S FSH will respond with a ‘Syntax Error’ acknowledge message (“1”<cr>).
Note: When using remote control commands and the sweep time is less than 30 ms (e.g. Zero
span) the measurement will stop until the complete command is received (in this case all
interrupts are switched off due to the processing of all data points).
