1.2 MS Matrices
MS-Series stands for Multiple Switches. It is a matrix where a number of
independent switches are populated on the rear panel or inside the matrix
enclosure. From an RF point of view the switches are not interconnected and
all switch’s RF ports are available to the user on the rear panel of the matrix.
Depending on the size of the switch and the quantities needed, the matrix size
can grow from 1RU to 4RU (or even larger).

Example of an MS series matrix with four independent SP4T switches.
Part Numbering Examples:
MS-2U18S-4/X-GPIB A Multi Switch matrix with the following characteristics:
2U, 18 GHz, SMA, 4 transfer switches, GPIB
MS-2U26S-4/6T- GPIB A Multi Switch matrix with the following characteristics:
2U, 26 GHz, SMA, 4 Terminated SP6T, GPIB
MS-4U18N-12/10- GPIB A Multi Switch matrix with the following characteristics:
4U, 18 GHz, N connectors,12 SP10T, GPIB
The part numbering is interpreted as follows:
MS-[chassis size][frequency][connector]-[number of switches]/[type of switch]-[remote control
type]
[chassis size]: 1U | 2U | 3U | 4U etc.
[frequency]: 12 (for 12.4 GHz) | 18 (for 18 GHz | 26 (for 26.5 GHz) | 40 (for 40 GHz)
[connector]: B (for BNC) | N (for N) | S (for SMA) | K (for 2.9 mm)
[number of switches]: 1 | 2 | 3 | 4 | 5 |… |16 (or more if chassis size allows)
[type of switch] : 2T (terminating one port DPDT Æterminated SPDT) | X (for DPDT)
| 4 (for SP4T) | 6 (for SP6T) | 8 (for SP8T) | 10 (for SP10T) |12 (for
SP12T).
If switch type is terminated, add ‘T’ to the number.
Example: 6T (terminated SP6T)
[number of switches]/[type of switch]: If different switch types are combined, repeat this section
as needed.
Example: MS-1U18S-2/X-2/6T-GPIB
[remote control type]: ENET (for Ethernet, RS-232, USB) | GPIB ( for IEEE-488, USB)
